Trying to fix a mermaid diagram in this editor is impossible.  Please allow for resizing of the editor!  The current editor is very narrow for code editing.

This is so important. A 500px width is way too narrow. As a user, I should be able to adjust the editor width to be as wide as I want without restriction.

This is such an easy thing to fix. It would make our lives so much easier. Please let us resize the width of the mermaid editor.
