To work around this, I was going to use a zero height line but could not achieve the effect after a couple tries. While I achieved vanishing line height in a fundamental mode buffer using an actual newline with text properties, I could not reproduce the effect in a fontified buffer, where I needed to use an overlay. I messed around a bit with 'before-string etc. I'm aware this might be a display limitation and want to confirm before labeling my user's issue accordingly.
