Phanpy (three-column setup) cannot get to third boost under 1,600 x 900 window size

### Site

phanpy.social

### Version

2026.01.07.2e1d0c4

### Instance

g0v.social

### Browser

- LibreWolf 146.0.1-1 on Windows 11

### Bug description

The default window size of LibreWolf is 1,600 x 900. LibreWolf user does not get to change this unless they disable RFP (Resist Fingerprinting) entirely. Unfortunately, at this window size, Phanpy cannot display boosts properly under the three-column setting. It will display the first two boosts correctly but unable to click past the second boost. The third boost will be displayed partially.

### To reproduce

1. Change browser window size to 1,600 x 900.
2. Set up Phanpy so that it has three columns. One of the columns should be 'Following' to display boosts from other people.
3. Once there is a consolidated boost strip with four or more boosts, try to get to the third boost and beyond.

### Expected behavior

Observed behaviour: user cannot get to the third boost and beyond.

Expected bheaviour: user should be able to click past second boost and get to the third boost and beyond.
