Describe the bug
(Classic) I wanted to create a String edit box in Custom Options, and the feature "Large input" doesn't work, the edit box doesn't turn into multi-line box and stays 1 line high.

Do you have an error log of what happened?
I didn't get any Lua errors.

Screenshots

Did you try having WeakAuras as the only enabled addon and everything else (especially something like ElvUI) disabled?
Yes, it had the default skin, but the issue stayed the same = single line edit box.

Which version of WeakAuras are you using?
2.14.6 - Classic

Was it working in a previous version? If yes, which was the last good one?
I didn't test it in other versions.
