What happened?
Description
Regular Plain Text fields all auto-expand as you type into them, ensuring that content isn't hidden from view or behind a scrollbar. The new Alternative Text field appears to be locked at two/three rows, and does not expand beyond that, making content harder to read.
Steps to reproduce
- Create any Asset with the Alternative Text field enabled
- Type into the box until you exceed the existing height.
- A vertical scroll bar will appear; text area does not expand.
Expected behavior
Text area to expand to fit the content, in the same way that Plain Text fields do.
