underscore (italics) markdown in preview disrupted by cursor logic

[clem4962]

Add a fresh paragraph to a page, highlight it, then hit the Italics button, then Preview. The italics will not render (it will display plain text with underscores):

_my new text_

There are other variations, such as leaving the cursor on a subsequent blank line etc, but all occur because the cursor logic in renderer.py has modified the line to this:

_my new text_CuRsoRm4g1cW0Rd

which the markdown rendering no longer recognises.

(Using asterisks instead of underscores works fine.)

Possibly this might be fixed by changing the magic cursor word to an html comment, eg <!--CuRsoRm4g1cW0Rd--> ? This worked in my somewhat limited testing.

OTOH, I'm not too sure what purpose the cursor processing actually serves. Is it required in some other use case other than preview?

Hey @clem4962, I can reproduce this bug.

You are right, the CuRsoRm4g1cW0Rd is used for previewing the location of the page where you placed your cursor, so that you dont have to scroll and search for what you've just edited.

If you mark a paragraph, hit Italics as you described and place the cursor below, before you hit Preview it's rendered correctly.
