sorry ，I cannot upload the image.
Can you  reproduce the problem ?

when I am playing the vedio on  webpage ,check the source code of the webpage 
These are codes about sliding advertising strips.translate3d :X-offset = 360px
<div class="rmb-carousel-wrapper">
	<ul class="rmb-carousel-scroller new-style" style="transition: all 0.3s ease; transform: translate3d(-720px, 0px, 0px);">
		<li class="rmb-carousel-item" data-index="3" style="display: list-item; transition: all 0s ease; transform: translate3d(-360px, 0px, 0px);">...</li>
		<li class="rmb-carousel-item" data-index="0" style="display: list-item; transition: all 0s ease; transform: translate3d(0px, 0px, 0px);">...</li>
		<li class="rmb-carousel-item" data-index="1" style="display: list-item; transition: all 0s ease; transform: translate3d(360px, 0px, 0px);">...</li>
		.
		.
		.

playing in fullscreen :	X-offset = 720px
<div class="rmb-carousel-wrapper">
	<ul class="rmb-carousel-scroller new-style" style="transition: all 0.3s ease; transform: translate3d(-1920px, 0px, 0px);">
		<li class="rmb-carousel-item" data-index="3" style="display: list-item; transition: all 0s ease; transform: translate3d(-640px, 0px, 0px);">...</li>
		<li class="rmb-carousel-item" data-index="0" style="display: list-item; transition: all 0s ease; transform: translate3d(0px, 0px, 0px);">...</li>
		<li class="rmb-carousel-item" data-index="1" style="display: list-item; transition: all 0s ease; transform: translate3d(640px, 0px, 0px);">...</li>
		.
		.
		.
		
playing in PIP window :	X-offset = 192px		
<div class="rmb-carousel-wrapper">
	<ul class="rmb-carousel-scroller new-style" style="transition: all 0.3s ease; transform: translate3d(-192px, 0px, 0px);">
		<li class="rmb-carousel-item" data-index="3" style="display: list-item; transition: all 0s ease; transform: translate3d(-192px, 0px, 0px);">...</li>
		<li class="rmb-carousel-item" data-index="0" style="display: list-item; transition: all 0s ease; transform: translate3d(0px, 0px, 0px);">...</li>
		<li class="rmb-carousel-item" data-index="1" style="display: list-item; transition: all 0s ease; transform: translate3d(192px, 0px, 0px);">...</li>
		.
		.
		.

.Then I close the PIP window with the Close button 
.Open chrome ，the vedio will be playing on  webpage
However：X-offset = 192px   ---->  The banner above the video is in chaos
<div class="rmb-carousel-wrapper">
	<ul class="rmb-carousel-scroller new-style" style="transition: all 0.3s ease; transform: translate3d(-192px, 0px, 0px);">
		<li class="rmb-carousel-item" data-index="3" style="display: list-item; transition: all 0s ease; transform: translate3d(-192px, 0px, 0px);">...</li>
		<li class="rmb-carousel-item" data-index="0" style="display: list-item; transition: all 0s ease; transform: translate3d(0px, 0px, 0px);">...</li>
		<li class="rmb-carousel-item" data-index="1" style="display: list-item; transition: all 0s ease; transform: translate3d(192px, 0px, 0px);">...</li>
		.
		.
		.

The advertisement bar above the video uses the translate3d timing offset(the length of the video area is specified),
 when playing the video using the mate10 webpage ,the x-offset = 360px ,
 when playing the full screen, the x-offset = 640px 
and when playing in PIP window, x-offset =192px; 
but after I closed the PIP window directly, open the browser again, the x-offset should be 360px, but the value obtained is still 192px; thus the advertisement bars seem to overlap;
Is this website problem ?

It should be like this,this web page changes the value of x-offset (x-offset = window.innerWidth) by listening to window changes (window.onresize()), but when the PIP window is closed directly, this notification  is not triggered, so that the value of x-offset is not changed.

Tested the issue in Android and able to reproduce the issue. 

Steps Followed:
1. Navigated to https://sv.baidu.com , played video in fullscreen
2. selected the home button and the video is playing in PIP window
3. Closed the PIP window
4. opened chrome --- Observing overlapping of content in bannerThe banner

Thanks!

When will this issue be handled ？

peconn@ Does comment #6 ring a bell?

When you reopen Chrome, isn't window.onload() called? Can't you resize the ad banner there?

 https://sv.baidu.com  ---->  this page resize the ad banner by window.onResize()
and this page is not developed by us.
I just found this  bug
