unclear behavior for long titles longer than 255 chars

[grnd-alt]

when editing the title inline (by clicking on the title) and inserting text longer than 255 characters, it can't be stored.
The request returns a 400 as expected. BUT there's no user feedback at all. The title stays at the inserted text longer than 255 and is only refreshed on a state update.

Steps to reproduce

1. create card
2. edit title
3. insert more than 255 chars
4. move card to other column

expected behavior

some error message/red outline around the input field

actual behavior

everything looks normal, title resets without feedback

proposed solution

remove inline editing as already discussed here, and approved by design.

Maybe we should discuss how best to handle it then, since it was already discussed previously to remove the inline editing, from what I can see
