Photos in the timeline are getting skipped when scrolling upwards from the bottom

[macphoenix1000]

The bug

Opening Immich in Safari 18.3 on a MacBook Pro M2 Max with macOS Sequoia 15.3.1. Scrolling down in the photos timeline all way down to the bottom. Then scrolling up step-by-step. Suddenly Immich skips some rows of photos automatically. Feels like Immich is jerking. Only happens in Safari, not in Firefox.

Additional information

Error only occurs in Safari and does not show up in Firefox 135.0.1. Immich app 1.126.1 build.194 on iPad Pro M4 is also fine and doesn't show the error.

In Safari there are add-ons installed for Synology Photos (Synology Image Assistant) and Bitwarden.
