Can't look or edit typewriter text keyframes for size setting

I want to animate the typewriter text using keyframes so it moves around the screen. The animation is visible but they keyframes don’t appear on the “timeline”.

Other settings do appear when keyframing them as shown in the video. I’m on the version 26.1.30
and my operating system is Linux Mint, installed Shotcut through flatpak.

confirmed. This is fixed for the next version 26.2 (not in the beta)
