[6.0.0 regression] Disabled horizontal scrollbar appears when reaching max-height

[andersk]

When using autosize on a <textarea> with a CSS max-height, after typing enough content to reach the max-height, autosize 6.0.0 and 6.0.1 unexpectedly adds a disabled horizontal scrollbar in addition to the expected vertical scrollbar.

Based on git bisect, 8389fc92f14a1485e2f949941ef4e3db2a222fcd is the first commit with this issue.

This prevents Zulip from upgrading to autosize 6 (zulip/zulip#25087).

• 6.0.1 (bad): https://jsfiddle.net/anderskaseorg/mtn9cb83/2/

I didn't upgrade too. In the commit supplied above, before it was setting overflowY to scroll, now it's setting overflow.
