Bug - TextArea - autoResize height issue if parent has explicit height

[mcoker]

Here's the issue - https://codesandbox.io/p/sandbox/vigilant-aryabhata-42n8xv?file=%2Findex.tsx

Looks like it's due to this line in setAutoHeight that resets the form control wrapper height to inherit when the function runs.

patternfly-react/packages/react-core/src/components/TextArea/TextArea.tsx

Line 63 in 031fba5

parent.style.setProperty('height', 'inherit');

If the form control wrapper's parent has an explicit height set, inherit will use whatever that parent's height is. You can also see the bug if you look at the full-page example for the autoresize textarea. The form control's parent has height: 100% (occupying the full viewport height), so the textarea is full height, too.
