Layout resizing when mousing over progress bar

[mjmeintjes]

I've embedded the player on my page using <script src="https://cdn.podlove.org/web-player/5.x/embed.js">

Everything seems to be working, but then after a while the layout starts jumping around when I mouse over the progress bar.

This happens in Firefox and Chrome.

Here's a video to better explain: https://github.com/podlove/podlove-ui/assets/72253/1cc5e008-83a6-4faa-b9c0-e3aaf6c2f3e9

It looks like this is related to chapter lengths. I've truncated all my chapter titles to 70 characters and the layout resizing seems to have stopped.
