Chromium-based browsers prevent address bar from hiding when accessibility service is running

What happened that you did not expect?

After granting KeyMapper accessibility permissions, every Chromium-based browser on my device stopped hiding when scrolling down. Brave, Chrome, and more.

After some research, I discovered this has to do with the accessibility settings: redlib.catsarch.com/r/chrome/comments/179n1il/address_bar_and_tab_bar_wont_hide/k6c7des/?context=3#k6c7des.

This does not happen with other apps I have, currently and in the past, with the same accessibility permission. Disabling KeyMapper, while leaving other apps with the same permission, returns the browsers to their normal state. Disabling every other app but KeyMapper leaves the browsers broken.

What did you expect to happen?

Chromium-based browsers to work as they normally do. This is more than an inconvenience on phones that have OLED displays.

What would the developer need to do to reproduce the bug?

1. Grant accessibility permission
2. Go to a Chromium-based browser and open a site that has scrollable content
3. Scroll up
4. Address bar permanently on the screen

@jambl3r The title is inaccurate. It now blames scrolling, but it is the victim if anything. At the very least it should instead say on Chromium-based browsers prevented from hiding their address bars.
