Galery preview "jumping" on larger folder

[petrkr]

Describe the bug
In folder where are more files than (do not know how much) after scrolling down it blanks, slider will gets bigger (like there are not too many files) and if I continue scrolling down, it jumps to begin of the page.

Sometimes there instead of black canvas will jump probably rest of photos, but they are all over each other.

It was introdced in some 28 like two/three released back, do not remember exactly as I am not using often web galery.

In time of writing this I updated to latest 29 version

To Reproduce
Steps to reproduce the behavior:

1. Go to 'Photos --> Folders --> Select folder with lot of photos (l tested 1000)'
2. Start Scrolling down
3. See error

Expected behavior
See whole galery
