Is tooltip-mode turned on?

We'd like to focus on improving the user experience of the core features
first.  If these issues are cleaned up before 9.7, I will work on
polishing the live previews feature.

There is no documentation for live-previews yet.  If you would like
to try it -- and I encourage you to -- you could set:

(setq org-latex-preview-auto-generate 'live)

and then turn on `org-latex-preview-auto-mode'.  The variables
`org-latex-preview-throttle' and `org-latex-preview-debounce' control
the responsiveness of the live previews.

If the live preview is not removed automatically after you move away
from a LaTeX fragment, you might have to manually eval
`(org-latex-preview-live--clearout)'.  This is one of the many edge
cases with the feature that need to be handled.

Thank you! The testing is very helpful as well.
