Hello.

Org 9.3.6: when inserting the entry by capture mechanics, it narrows buffer in a way that cursor can be moved to the last line, which is the beginning of next (non-capture template) line in the original unnarowed buffer.

So this allows to: start capture, move point to the very last char of the narrowed buffer, insert something. If this line in unnarowed buffer was start of heading, it breaks structure of document.

This is patch in attempt to fix it. I followed same approach as in org-capture-place-item function.

Thanks,

Alexey
