Yes, seems to be related to #3231

Describe the issue you encountered:

Periodically after launching the browser, the close button and right click on the Bookmarks toolbar become inoperable. The following error is in the console.

The error message is repeatedly reported on all mouse movement events in all open tabs, as well as on a close button press.

• Platform (Win10):
• Brave Version: 0.12.3
• Steps to reproduce:
  1. This is reproducible on only a fraction of the launch attempts (~10%)

there is a good chance that error message is unrelated. It happens frequently since upstream made a change to the remote api. If you see it happen as a directly result of some action then it might be related

[bridiver]

actually in this case it might be related because line 191 is an emit for a sync ipc call

[aekeus]

The error message is triggered each time the mouse is moved over the tab when the browser is in the described state. It is not sent to the console in normal browser operation.

is this windows only?

[aekeus]

Yes, I can only trigger it on Windows 10.

This could be the cause, I'm pulling in the commits from upstream electron which has them only in 1.4.1, we're on 1.4.0 upstream.

(just for tracking purposes) It seems issue was first seen with #4380 (comment)

Since this only happened for @aekeus and it was confirmed on his machines, I think the only steps for QA are to check that the common windows interaction items work properly.

If there are other concerns for QA, (like zoom, resolution, etc.) please be sure add a comment.
