When creating URLs using BBCode with a dynamic expression containing a colon in the Rich Text Editor, an invalid URL is created and "https://bubble.io" is prepended.

Dynamic expressions are inserted "as is" and they often contain colons. As a result, an invalid URL is created once the Rich Text Editor is toggled. To prevent this, you'll want to refrain from toggling the Rich Text Editor for links created from dynamic expressions.
