Can't see tooltip completely on rich text Input. Bug?

Hi Bubblers,
does anyone of you recognized the same problem and has a solution for it:

I’m using the “Rich Text Input/editor” plugin by Bubble. When I use the “tooltips” for design settings (e.g. H1, bold,…) and create just a single line (mark the text and try to edit the design) , I can’t see the tooltip completely:

But when I add 2-4 more lines, then I can edit the first line easily:

Is that a bug, or can I fix this?
Thanks in advance
