The changes work well for me 👍
I verified that:

• the scm input is visible and has a correct minimum height
  • also verified it expands correctly when multiple lines are present
  • also verified that validation looks correct
• the scm input is persisted when the application is reloaded
• the padding for the entries is correct when using both the tree and list view modes

I verified the specific case in #7794 where a new workspace, never before opened, is opened. The input box is now immediately the correct height without having to update or anything to get the correct height. Thanks for fixing that.
