Thanks; continuing on the patch itself as bug#58271.

Are you mentioning the case when the xwidget view is deleted via
‘delete-xwidget-view’? If that’s the case, the patch on bug#58271 will
automatically recreate the xwidget view. Can the xwidget itself get
deleted when a referencing xwidget view still exists in a buffer?

I’m unfortunately not *that* knowledgable on xwidget internals; the very
first original patch was written by Jaesup Kwak, I’ve been slowly
expanding my understandings.

I found that documentation on various parts of xwidgets were very light;
while the functions related to xwidget views are exposed in elisp, seems
like documentation on them were non-existent. I’m still having a hard
time understanding on how the xwidget system is designed to interact
(e.g. it seems from the code that one window cannot contain two xwidget
views pointing the same xwidget – is this a bug or is it working as
designed?); do you have any pointers on this?

Thanks.
