doesn't work on some nodes

[delcroip]

Hi,

thanks a lot for that work

I did test it and it worked for some nodes (mxcell) but not all (object)

Upon activating markdown on node I am getting that error

e.replace is not a function

then I am getting this one while trying to edit that same node

Uncaught TypeError: t.firstChild.getAttribute is not a function
``

can you provide a video

what nodes don't work? I have found that it's not suitable for the table.

I did some error handling and gave prompts about whether the current cell supports Markdown syntax. Is that OK?
