MCL-21145Unable to log because launcher opens an internal web browser that is not accessable
On clicking on "Microsoft Login", it opens a broken web browser. The browser is broken because it does not honor my color theme and loads an overbright and oversaturated page, and doesn't honor the system background color either before the page is rendered.
This is not a Windows system, but the equivalent windows setting is High Contrast Black.
This issue has been filed publicly after Mojang support has closed the private support case after a week of them making no progress and having been hold-abandoned by Microsoft support.
Here are some screenshots of MultiMC able to log in; however this is not a solution because MultiMC is currently not working. Implement this, and you won't have an accessibility bug anymore.

Hi there!
Could you answer few questions regarding this issue, it will help with the investigation:
This ticket will automatically reopen when you reply.
> Does this issue occur on newest version of the Launcher?
Yes. Launcher auto updates.
> Do you have enough free space on your disc drive?
Yes. df says the disk is only half full.
> Do you have Chrome browser installed?
Yes, but only for dependency management. It is utterly unusable due to having a very similar bug. Firefox is the browser I use.
> Do you use VPN or any of the incompatible software on machine you try to log-in?
No.
> Could you provide us with more in-depth repro steps?
Set environment variables:
QT_ACCESSIBILITY=1
QT_QPA_PLATFORMTHEME=qt5ct
GTK_THEME=Adwaita:dark
SAL_USE_VCLPLUGIN=gtk
MOZ_ALLOW_GTK_DARK_THEME=true
Start launcher, click on "Log on with Microsoft."
I am convinced the rendering of the page will be the same on my computer as yours; but you do not have my eyes. To truly experience the problem you would need my eyes.
Hi there!
I noticed that you are using MultiMC Launcher. Does this issue occurs on MultiMC specifically, or on the official Minecraft Launcher?
This ticket will automatically reopen when you reply.
This is a bug in the stock launcher. Had you attempted to verify you would find the log in with microsoft button does not honor the dark theme; however you did not.
I uploaded snapshots of MultiMC to demonstrate the problem is fixable.
