Seems to be regressed by #711, see #711 (comment)

This PR seems to break the auto dismiss of the doc frame after it has been focused in (for scrolling and reading on the docs) and out.
I've bond tab to lsp-ui-doc-focus-frame and q to lsp-ui-doc-unfocus-frame.
Here is the current behavior

As you can see, it's broken and I have to press Tab twice for the focus to be moved to the doc frame.
