"Is on floor" property is not detected correctly

Problem Description

Hello.

There is an specific situation when Is on floor property do not work properly, for example if you create an object(enemy) and set 2 behaviors: jump-thru and platform together, then this object falls over another object(object2) which have behaviors: jump-thru an sine(with vertical movement), and you jump with the main player (using platform behavior again) and fall over the first object(enemy) which is on the object 2 that is moving up and down, the Is on floor property is not detected correctly.

Having a Platform behavior and a solid behavior makes no sense. Maybe that's the issue.

Yeah, that's true, but I have not many options to do this. I think that should be possible, because when the object enemy is over an solid object immovable (like tile map) and the main player is on enemy object (green box), the 'is on floor' property works fine, therefore the main player animations work fine as well:(notice the main player animation run appear)

However when the enemy object is over the yellow object (which have sine behavior) and the main player goes above from enemy, the main player animation run do not appear, because the 'is on floor' property never is detected:

Closing as won't fix: the platform behavior is not designed to work on an object which is also solid or jumpthru, as the "2" object is. Workaround: either remove the Platform movement from the "2" object, or its jumpthru behavior, or don't rely on 'Is on floor' and use some other detection instead (e.g. 'is overlapping at offset').

Can to use various behaviors together without issue would be great!
