Bug: Player model clips into floor when crouch jumping

[Equalizer5118]

Describe the bug

When couch jumping with mv_duckjump enabled, the playermodel will clip into the floor. This only happens when crouchjumping with crouch then jump, and not jump then crouch. Can be seen both in thirdperson and in mirrors.

Normal crouch

Crouch + jump (pressing crouch before jump)

Issue Map

N/A, easily tested here: https://www.mediafire.com/file/rq674gsa7ptjehq/mirrortest.bsp/file (simple map I created to test prop_mirror. saves having to use sv_cheats and enabling third person)

To Reproduce

1. Open any map
2. Enable mv_duckjump
3. duckjump, but press crouch first
4. Observe bug

Operating System

Tested on Windows 11

We're going to be removing the dynamic movement stuff (all mv_ cvars)

[Equalizer5118]

Ok, I don't think its a problem with the variable though. That just enables the ability to duck and jump right?

[JJL772]

well all of that code is going to be removed in favor of a different system

[MyGamepedia]

Maybe stupid question but: does it mean that old movement (as in Portal/Half Life 2) will not added ? I'm pretty sure that it'll can call problems like this.

[JJL772]

Yes, HL2 movement will be added. This isn't that though, this was a sloppy attempt at porting HL2 movement features to Portal 2's movement

[MyGamepedia]

Ok. By the way, how hard will be to add it ?
