Description of the issue:
When switching back to some of multiple Brave tab from other application (or after focusing desktop first), just when the tab got focus it is disconnected from the actual Brave window and moved to a main display.

Steps to Reproduce:
-Have some opened browser tabs
-Try to switch between some other application and a random browser tab.

Actual result:
Randomly the browser tab which the user want to focus is desconnecting from the main browser window and moved to a main display.

Expected result:
Selected tab is focused and displayed without disconnection from the browser window.

Reproduces how often:
This problem seems to be very rare when trying to reproduce, appears more often when there is some greater use of a PC resources. Playing video on a browser, some resource demanding application or game started.

Operating System and Brave Version:

• System: Windows 10 Home
• Brave version: Version 1.26.74 Chromium: 91.0.4472.124 (Official Build) (64-bit)

Additional Information:

• This does not have a connection with a missclick, doubleclick or dragging page out of a browser window
• When focusing already displayed tab then sometimes instead of disconnecting the tab url is changing and it looks like the whole content of previously focused window is copied to an url. the “413. That’s an error. Your client issued a request that was too large. That’s all we know” error appears.

Hey @Darki ! Welcome to the community

Is the browser really laggy during the switching between and application and an Ad? Do you have any extensions installed eating up your resources? You can check this by going to your Menu Icon → More Tools → Task Manager.

To be on the safe side, disable all extensions to see if the issue persists.

I have disabled all extensions, and yes I had some heavy extensions, but this does not resolve this problem.
