Original GitHub issue: https://github.com/floccusaddon/floccus/issues/836

Describe the bug

I suspect there is a memory leak in floccus.

To Reproduce

Steps to reproduce the behavior:

Start Microsoft Edge (I am using 89.0.774.27 at the moment)
Set up Nextcloud account
Sync
Open Browser Task Manager
Leave browser open for 24 hours

Expected behavior

Memory usage of floccus add-on should stay the same (something between 20-40MB; it's higher during sync but should free up memory afterwards). But after some hours, floccus has reached 400MB. I accidentally left browser running during weekend and on Monday, Browser Task Manager showed more than 3GB RAM usage just for floccus extension. Whole browser was sluggish (not even another website was loaded). After disabling extension, browser recovered.

Desktop

OS: Windows 10 20h@ 19042.804
Browser: Microsoft Edge
Browser Version: 89.0.774.27
Floccus version: 4.4.8
Floccus sync method: nextcloud folders
