Multiline TextField fullWidth is not working

[anubit67]

Current Behavior 😯

When I set the "fullWidth" on a multiline TextField it is not taking the fullWidth. If I add a normal (non-multiline) TextField it takes the fullWidth.

Expected Behavior 🤔

The multiline TextField should take the fullWidth like a normal (non-multiline) TextField takes.
