💡 Background and solution

The TextArea component older then 14-th version of antdesign-blazor has the "affix-wrapper-disabled" class on span element of textarea wrap. It looked like this

But at the moment we don't have the class

We used it in our project for deactivate the textarea hover.
Solution is to add "affix-wrapper-disabled" class to wrapper span of textarea, as it has already done for inputs(base class) and as it was adding before in yonger then 14-th versions.

@ElderJames thanks for comments. I guess I've done everything as you said and debug it. I've checked a test locally for it and pass it. Should I do something more for the issue?
