Placing the cursor at the start of an inset and pressing the backspace
key destroys the inset and makes its content part of the surrounding
text. However, if the inset is the *only* item in a paragraph
environment (list, Quotation, etc.) then not only is the inset destroyed
but so too is the environment, which becomes a standard paragraph.
Writing [note](note contents) to denote a note inset,
1. [note](blah blah blah)
(a) sub-item
(b) another sub-item
displays in the pdf as
1. (a) sub-item
(b) another sub-item
which may what is desired, but if you feel the "blah blah blah" should
be made visible in the pdf and put the cursor before the first "blah"
and press backspace, the result is
blah blah blah <-- a standard paragraph
1. sub-item
(a) another sub-item
What I expected was
1. blah blah blah
(a) sub-item
(b) another sub-item
This seems to apply to all insets (I've also tried footnotes, margin
notes, minipages, ERT), not just notes.
