Styling / scrollbar issue

[eXpl0it3r]

Steps to reproduce

• Get the starterkit with Kirby 3.4.4 (maybe other versions also apply)
• Change one of the blueprint to take a type: markdown field
• Open the panel page
• Start entering some text

Actual Behavior

• The height of the text box is to small to start with
• The scrollbar is shown from the start
• After entering two lines of text, the second line is already vanishing to the top, out of the text box
• Doesn't matter if the font was set as regular or small

Expected Behavior

• The height should at least cover two lines of text from the start
• There isn't really a need for a scrollbar if the text box keeps expanding correctly
• The text should not be moving out of view (after two lines of text), but the text box should expand to the correct size

I just took a look at CodeMirror's documentation and setting the scrollbarStyle to null instead of native already got rid of the scrollbar for me. But there's still some spacing issue, which I guess comes from the toolbar being in the same space as the text entry field.

I've some "fixes", but they seem more like patches than actually solving the issue. Posting here, just in case someone else is interested in them. 😅

The scrollbar issue is fixed.

I have added a size option.
