Bug description

Hi all. This one is probably very low priority and really minor but I'm nothing if not pedantic, so hopefully this helps with overall stability. Basically, when Android 13 switches from normal to power saving mode, apps go through a bit of a weird makeover where they switch to dark mode and the screen refreshes. During this time, I was typing a message and some of my text was lost. It was less than one sentence so nothing of import, but putting this here in case it is useful to developers.

Steps to reproduce

• Open signal at or around 26% battery
• Begin typing a message (in my case, it was a message using the "reply" feature)
• Continue typing until the battery hits 25% (or whatever setting your default battery saving mode is)
• Android will switch to power saving mode, the screen will refresh

Actual result: Describe here what happens after you run the steps above (i.e. the buggy behaviour)
Approximately the last 5 seconds of text you just input will be missing.

Expected result: Describe here what should happen after you run the steps above (i.e. what would be the correct behaviour)
No input text in a message field should be lost.
