Block Editor: Link control displays scrollbars on toggle

[t-hamano]

Description

In the new link control component, an unnatural scroll bar appears when toggling settings.

I have confirmed this issue in both Chrome and Firefox on Windows. On Mac, you might be able to reproduce this by changing the "General > Show scroll bars" setting to "Always".

Step-by-step reproduction instructions

Set a link to the text and click the settings toggle button.

The new settings "drawer" isn't shipping with WP 6.2.
