Query-based contexts have weird and unusable input behavior if I go "create context" from Search screen

I got to this screen by first running this search, then clicking "create context." Weirdly, when I try to edit the context (say, to add ^github\.com to my repo filter, for example) it jumps my input cursor to the end of the input every single time (the loom is me repeatedly trying to enter input earlier than the end of the existing input).
