Major - Sequencer - Relative keyframes cause unwanted transformations

So I wanted to make a relative animation of a door opening, which then can be used from every angle if I rotate that door. So I made a sequencer animation and set the animation to relative.

However, strange things happen when I try to set any keyframe, the object reacts in completely absurd ways.

Here is an example, rotating the door in a relative keyframe also scales it and moves it.

That doesn’t seem intended
