Why does my keyboard freeze after a search?

Hello! So long story short I've been looking to switch my default browser to Firefox and I would've done so by now if it wasn't for this small issue. It's not anything super important, but it has been mildly annoying to deal with. I can't say for certain how long this has been an issue in general since I've only just started trying out the Firefox search widget about a week or two ago. The issue happens every time I use the search widget and seems to happen infrequently when I use my private tab shortcut too, but doesn't happen when I use the app directly however. After a initial search (when you first open the widget/tab), my keyboard would freeze on screen (sometimes fully opaque and other times a bit transparent in a similar way to a screen burn). I can only fix it by either exiting and re-entering the app/tab or by clicking on a link and having it redirect me. I have zero clue as to what could be causing this or if it is some kind of bug? Any help would be appreciated, thank you!
