I have a comment field populated with C. 500 words, and the comment box/window is sized appropriately to fit the entered text. When I enable inline editing, the comment box changes to a size far in excess of what is required, making scrolling through records cumbersome. When inline editing is unchecked again, the comment box reverts to its original size, again fitting the entered text.
Just following up on this, when you have a Note/Comment field in Noloco (a long text field from Airtable), you experience the same behaviour as outlined above when you edit a record.
The text displays appropriately sized when viewing the record, but the box expands far more than required when you go to edit the record. The same thing happens if you edit via an action button.
