Here is another interesting observation. With something in the clipboard, I started up Sigil. Then opened an epub3 ebook that had css, javascripts, and of course a content.opf to go with its xhtml files.
I tried selecting text in the xhtml and css tabs and they appeared slow. I tried selecting text n the javascript tab and in the content.opf and both were fast! No slowdown. The javascript one did not have any syntax highlighting. So i thought it might be the syntax highlighting we do. But then the content.opf did have syntax highlighting and it was fast.
The css and xhtml both have syntax highlighting and are slow. A CodeView widget is used for all of these. The only thing different is the type of Tab widget being used.
Hmm....
