Maybe a bug: I have 13 static partitions. I am on the asset materialization screen of dagit, and am using the "filter partition" selection box. When I try to scroll down to select partitions low on the list, the last few items viewable on the list start to "flicker" and it won't let me click on an item to check/uncheck it. I've tried this on Microsoft Edge and Chrome. Dagster 1.3.1.

Sorry that you're hitting this! We have a potential fix coming out next week.
