QSlideItem breaks with contitionnal side templates [repeat from quasar v2.14.3]

[CCTVcalc]

What happened?

I use QSlideItem to deal with a dynamic list of items.
Base on #16902

What did you expect to happen?

When I try to slide from right to left, the click handling and subsequent slide don't always trigger — it's quite inconsistent.

How to reproduce?

Click and release before the action triggers. At some point, the displacement stops working.
