Share preview bugged

[ClaraCrazy]

Hey there! I used your app for a while but I just noticed that when sharing a text file the preview on the share page is broken. You cant scroll at all

I tried using the normal text app for sharing but I'd rather have a fix for that since using the text app to do the sharing rendering process breaks other stuff.

I noticed that enabling your app overwrites the default <imgframe.text-preview> from default to "<div class="text-preview default-overridden" style="height: 346px;">"

If you could just let me know where it sets that, I could probably work on it on my own as well
