* I got sampled on Nightly for heartbeat. * Submitted a rating * The "fade out" animation started, making the heartbeat bar slide under the navbar * The content seemed to follow along? * Once the heartbeat bar was completely gone, the content suddenly jumped/resized to fill out the empty area at the bottom While this doesn't seem critical, it's not exactly an impressive/smooth UI.

I think this has been fixed, but you tell me. https://self-repair.mozilla.org/en-US/repair/?{%22runner%22:{%22alwaysRun%22:true}} <- safe testing.
