Show media in timeline reverted to "Always show"

### Steps to reproduce

I don't know how to reproduce this.

In Settings -> Preferences -> Moderation and safety, my setting for "Show media in timeline" was set to "In private rooms".

Earlier this week I started Element Web and saw an image in a public room. Today it happened again, so I checked my settings.

"Show media in timeline" had changed to "Always show".
