### Browser

- Firefox 135.0.1 (64-bit)

### Bug description

If I zoom to 110%, then I cannot navigate items in the deck of boosted posts - after pressing "->" button twice, it stops working.

The horizontal scrolling is also difficult to use.

### To reproduce

1. Enable multi-columned mode
2. Zoom to 110%
3. Go to a deck of boosted posts
4. Click "->" twice
5. Third time, it doesn't do anything

### Expected behavior

Everything works fine with 100% zoom!

### Other

This was actually a sort of big bug for me, because I hadn't realized the 110% zoom. I thought it was a general bug in Phanpy and had been living with it for months :)

But I suppose others that need the zoom are more blocked by it.
