Quote Block: Keyboard focus behavior differs from theme to theme

[t-hamano]

Description

When certain keystrokes are performed in a quote block, the behavior differs depending on the theme.

The quate block displays the block inserter button because the content consists of inner blocks. When the arrow-up key is pressed after the cite element has been given focus, its behavior varies depending on the theme.

Essentially, the first keystroke focuses on the block inserter and the second keystroke focuses on the innner block.

Curiously, however, in Twenty Twenty Three, the focus is skipped on the block inserter and given to the inner block.

I further investigated and found that this problem occurs when the cite element doesn't overlap the inserter.

I don't know if this is a problem with the block editor or the writing flow, or just expected behavior of the browser, but I am reporting it as an issue.

Step-by-step reproduction instructions

• Activate Twenty Twenty Three theme.
• Insert a quote block.
• Focus the cite element.
• Press the arrow-up key.
• Confirm that the block inserter disappears and the inner block comes into focus.

This is probably fixed after #60307?

#60307 seems to have removed the appender entirely, but when I select a block inside the Quote block, the quick inserter still appears in the top right. Is this intended?

Either way, I think this issue can be closed.

It's not just when selecting in list view, happens too without it. This is the empty default block inserter, it seems to be mispositioned. Let's rename this issue and fix it.
