Fixes #32800 (closed).
Here is a proposal for floating labels in textareas.
Solution
Patchwork of many comments/solution wrote in #32800 (closed). I tried to not add an extra class but it might be harder to maintain, I let you decide what would be better here.
Checks
- Works with everything in the page (even valid and invalid state, select)
- Works with sizes on input
- Couldn't spot any breaking change with the actual implementation
