Steps to reproduce the problem:
1. write a chrome extension with popup.html
2. the window size of popup.html may be 200 * 200
3. change the window size to 500*500 by js
4. about 5% possibility the new window will keep the size of original 200*200, so that only part of new window can be seen

Note: my own extension has this problem, and at first I think it is my bug, but today I install the Office extension developed by Microsoft, and it has the same problem

Microsoft Office:https://chrome.google.com/webstore/detail/office-online/ndjpnladcallmjemlbaebfadecfhkepb?hl=zh-CN

What is the expected behavior?

What went wrong?
window size stay the same after changing the size.
Attached file is the wrong effect of microsoft Office extension, and my extension is the same with it.
You can see the lower triangle is not occur so that we can say it renders error.

Did this work before? N/A
