Investigate flickering and slowness on filter search while plugins are loading

[goanpeca]

I see with the changes here and with latest main a little freeze when filtering things, maybe is worthy to create an issue to track that? Related more specifically with the flickering, I think I'm able to see that behavior in all the versions that I checked. Maybe that is related with changes caused due to other plugins being loaded which change the width used for other fields like author and then cause the plugin description space to be shorter? Maybe creating an issue for that could be worthy too? 🤔

I just did a fresh pull from main c48deb219038134fcbcbfa0e0fe9344781f6c84b here's what I get:

If i search for zar i don't get flickers, I think it's when the filter contains something that has already been loaded.
