[BUG] sticky bumpers dont shield tux from horizontal crusher hit

[Alasdairbugs]

SuperTux Version

SuperTux-v0.6.3-1540-g9f4496832

System Information

win11 64bit

Expected Behavior

Bumpers are in front of the horizontal crusher, so when tux hits them, the crusher should never be hitting and damaging Tux.

Actual Behavior

Instead, Tux hits the bumpers multiple times in a few frames, the crusher damages Tux, eliminating his momentum, the bumpers hit tux again multiple times in a few frames, and then the crusher goes past tux.

Steps To Reproduce Actual Behavior

Additional Information

tux is possibly phasing through the bumper. the bumper should act as a unisolid. for example: the bumper, facing right, can take things coming from the left, to the right, however, it will not let things pass from the right coming to the left.

in this case, because the crusher is moving to the right, its as if tux is behaving in the former: he is on the right, coming to the left.
