Textarea extra row in FireFox browser

Question

In FireFox HTML <textarea>s have one more row than specified in the property rows. If you are on FireFox you can see here:

<textarea rows="2">
This clearly has 3 rows and not 2 like you might think.
</textarea>

If you are not using FireFox right now then this is what the snippet result looks like to me:

Yes, it's an age-old bug in Firefox that still hasn't been fixed: https://bugzilla.mozilla.org/show_bug.cgi?id=33654.

There is a workaround:

textarea {
  overflow-x: hidden
}

I don't know if this workaround could cause any issue - is it ever possible for a textarea to overflow horizontally?
