Crash when OS turns to dark mode

[oppressor1761]

Description: Vanadium crashes when my phone switches to dark mode automatically (e.g., via Battery Saver or Sleep Mode ). This is a long-standing bug that is intermittent and difficult to reproduce consistently. I previously reported this in #509, but I closed it prematurely, mistakenly thinking it had been resolved.

Environment: Vanadium 145.0.7632.26.0. The only flag I've altered is chrome://flags/#darken-websites-checkbox-in-themes-setting=enabled

Reproduce: I only use incognito mode. So steps are

1. Browse the web in incognito
2. Wait for phone to enter dark mode automatically

@oppressor1761 Please test with Vanadium 145.0.7632.45.0 (in Alpha and Beta) along with Vanadium Config 154 (currently only in Alpha).

[oppressor1761]

I'll report here if I can reproduce it with alpha Vanadium.
Please note the issue cannot be reproduced 100%. It only occurs exactly when dark mode changes automatically meaning it's not a frequent issue.

Duplicate of #865?

[thestinger]

@An-anonymous-coder Does that involve a crash?

[An-anonymous-coder]

I'm not sure. All tabs get closed prematurely, which might be the result of a crash since "Close tabs on exit" is enabled.
