Memory leak playing videos on espn+ and audio on spotify

When playing video (live sports) on https://www.espn.com/espnplus or audio (music or podcasts) on https://www.spotify.com/ eventually the tab shows memory usage in the multiple gigabytes until the tab crashes with out of memory problem after approximately one hour of playing time. Hovering over the tab close button shows the memory usage.

This problem does not present when playing YouTube videos.

Here is ESPN+ after only a couple of minutes. Memory usage jumped by over 1GB in a minute.
