Wow, I can reproduce it with Canary on OSX. Looks amazing :)

 Issue 881547  has been merged into this issue.

Able to reproduce the issue on reported chrome version 69.0.3497.81 and on the latest canary 71.0.3544.0 using Windows 10, Mac 10.13.1 and Ubuntu 14.04

You are probably looking for a change made after 573382 (known good), but no later than 573383 (first known bad).
CHANGELOG URL:
The script might not always return single CL as suspect as some perf builds might get missing due to failure.

Can I take a look into this issue 
if this issue's difficulty is the same as the good first bug?
If so, a good start point might be helpful to me Thanks!

#21: You're welcome to look into it if you'd like.

I would probably start by tracking down the code responsible for creating or displaying the (empty) menu entries. Since UI strings like that are internationalized, you'll need to look in a .grd or .grdp file for the entry: <https://cs.chromium.org/search/?q=%5C(empty%5C)+file:.grd&sq=package:chromium&type=cs>

That reveals IDS_APP_MENU_EMPTY_SUBMENU which seems like a likely candidate. Code searching for uses of it: <https://cs.chromium.org/search/?q=IDS_APP_MENU_EMPTY_SUBMENU&sq=package:chromium&type=cs>

Points toward this file: <https://cs.chromium.org/chromium/src/ui/views/controls/menu/menu_item_view.cc?type=cs&q=IDS_APP_MENU_EMPTY_SUBMENU&sq=package:chromium&g=0&l=52>

So hopefully that gives you a place to start debugging. Please let me know if you do pick this up and I'll defer my own work on it.

#22: Thanks, now I start digging this issue. :)

I upload the CL to fix this issue. :)

Vamshi, could you please verify the fix once the CL lands in canary.

Bookmarks: Fix multiple empty bookmarks folders growing situation.

There is a bug with handling an empty bookmark folder.
This bug is reproduced when a bookmark bar has 2 folders
and at least one folder is an empty folder.

1. Click one of them, see the "Empty" placeholder
2. Move the cursor to the folder on the side
3. Move the cursor back to the previous folder,
   you'll see 2 placeholders
4. Keep moving the cursor between the folders
   and the placeholders count keeps growing.

To fix this bug,
I 've added the new member method 'HasEmptyMenuItemView()'
to check whether SubmenuView has at least one empty menu item.

So if submenu does not have visible children but also there is
no empty menu item then create an empty menu item.

This CL also maintain the functionality which was fixed
in crbug/852915.

Also, the unit test is also updated to cover this situation.

Re: C#25,
Verified the fix on Mac 10.13.1, Windows-10 and Ubuntu 14.04 using Chrome version #71.0.3572.0 as per the comment #0.
Attaching screen cast for reference.
