Hey @crutchcorn, is there a public timeline/kanban board/etc. somewhere where we can gauge an estimate for how long it will be until this might be worked on? I ask because I can see it's not assigned to anyone to fix in the meantime.

Hi
I have a question related to this issue:
At what point are onMount errors cleared?
Reading this I assumed they would be when the field is touched, but it turns out it is only performed when it changes (isDirty = true).
I don't know if that was the idea, or if it's a bug...
The only solution to avoid duplicate errors is to check the isDirty status in the event and perform validation accordingly?
I'm using v0.42.0 , as can be seen on this example to explain what I'm saying.
