Ballooning RAM usage on renderer process

### Steps to reproduce

1. Start Element
2. Idle and/or change rooms occasionally for hours or days
3. Renderer process goes from slightly over 200 MiB to hundreds higher
4. Close and restart Element
5. Renderer process is back to normal for the moment
6. Repeat and watch RAM usage climb again

### Outcome

#### What did you expect?
RAM usage to remain relatively stable or grow very slowly.
#### What happened instead?
RAM usage grows by hundreds in a single day doing next to nothing. The highest I've seen the renderer process go is slightly over 800 MiB, by which point I closed and restarted Element. I've also sometimes seen the main process grow over 500 MiB as well.
