Minimum Line Height being ignored for MOBI
I'm trying to convert a mobi file to a slightly altered mobi file (I wanted to add a cover image and increase the line height) and no matter what percentage I set the minimum line height to, it's being ignored. I've even tried 240% suggestion for double spaced and it stays the same when I open it on my Kindle. Other settings seem to stick just fine, like adding the extra 0.5em between paragraphs and the cover art I added, but that minimum line height is being stubborn. I'm on a new Kindle Paperwhite. Any suggestions?
