We had [a CSS
rule](f6d62e5cdc/app/client/packages/design-system/widgets/src/styles/src/text-input.module.css (L27-L30))
that was imitating CapSize behavior.

It worked okay with regular input but had no effect on TextArea. Fixing
it to work for TextArea did not seem possible no matter what CSS rules
or additional markup I threw at it:

<table>
<tr>
<td>
<img width="1252" alt="Screenshot 2024-07-12 at 10 32 30"

</td>
<td>
<img width="1270" alt="Screenshot 2024-07-12 at 10 32 40"

</td>
</tr>
</table>
</p>
</details>

Changing the inner spacing and removing that rule achieves the desired
results: elements are neatly aligned with similar/equal paddings. See
the example with additional elements alongside TextInput and TextArea
that verifies that vertical alignment is consistent:
