@dhruvang21 Thanks for the PR!

If we remove overflow:hidden, the scrollbar will not be displayed if the Top Toolbar is enabled:

Therefore, I think a different approach is needed. I would like to consider what approach is needed.

Hi @t-hamano,

You’re right that we cannot remove the overflow: hidden; property since it's necessary for the scroll bar. To resolve this issue, I’ve taken a different approach. While investigating, I noticed that the focus boxes appear correctly when the top toolbar is enabled, but not when it's disabled.

It seems the issue is related to the height difference: when the top toolbar is active, the height is set to 60px, but when it’s disabled, it reverts to 32px. I’ve attached a video demonstrating the issue and the solution, which involves setting a minimum height of 60px.

What do you think of this approach? If it seems appropriate, I’d be happy to commit the code.

Thanks!

@dhruvang21 Thanks for investigating. I also looked into it, and it would be a good idea to apply height. However, since the header is not expected to be more than 60px tall, it would be better to use height instead of min-height.

LGTM! Thanks for the fix 👍
