What changed / motivation ?
I noticed a couple small bugs in the Create/Rename file dialog:
My fix in this PR is to imperatively reset the input value when the dialog closes. I don't love this solution because it is relying on the fact that
defaultValueis updated beforeonClosewhen the form is submitted but it seems to work and fits in with the uncontrolled input usage. My initial thought was to use akeyprop on<FileNameDialog>element to force a remount when thedefaultValuechanges.Pre-flight checklist
