:asa, could you consider increasing the severity?

On Nightly 125.0a1 with Windows 11 on Night Sky HCM and Desert HCM too, I am not able to reproduce the issue anymore - hovering over the text elements or containers does not change the background of these elements, it only adds a border.

Simona, could you please check if the recent HCM work on Screenshots have resolved the issue on Windows 10 and/or Linux too? I do not have an access to either at the moment.

On Windows 10, I am still able to reproduce this issue on Firefox 124.0b8 (because the extension version of the Screenshots is still enabled).

However, on the latest Nightly 125.0a1, where the component version of the Screenshots tool is enabled by default ('screenshots.browser.component.enabled' is set to false) - this issue is no longer reproducible on Windows 10.

I also confirm that this issue is not reproducible on Ubuntu 22.04 x64.

Thank you, :Simona!

Moving this bug to the Screenshots component since it depends on the UI.

:Sam, the component version of the Screenshots has fixed the issue (refer to the comments #2 and #3 above) - maybe this bug can be closed as it's riding trains.

I added the blocker. We can close out a bunch of bugs once bug 1870127 is resolved and we are actually riding the trains.

This is fixed now that 1870127 is closed.
