Removing card with active text filter reruns the filter
Using the full deck (horizontal) layout, you can press the UP arrow and type stuff to filter your decks contents. Filtering Brawl decks in particular is very slow (much much slower than a simple text search should ever be! - it should take less than a second), so you don't want to do it too much.
If you remove a card when you have an active text filter, instead of simply removing that card and leaving the rest of the layout as is, it seems to want to re-run the entire filter again. This is a massive waste of time, energy etc.
Expected: removing a card simply removes the card, leaving the rest of the view as is, because it has not changed. The same goes for adding a card - you can run the filter on that card, check if the filter applies, and put it into the layout. None of the other columns are affected.
The only instance where removing a card should change the view is when it's literally your singular card that matches the filter, in which case the layout might change. But again... no need to rerun the filter, there's no cards left matching.
Please fix this, it makes deckbuilding very tedious.
