Steps to reproduce
1) Launch Nuke
2) Press "r" and navigate to a trackable video file. Load it.
3) Press tab and type in "tracker" to create a tracker node.
4) attach the tracker input pipe to the video file, then press 1 to select the tracker in the viewer.
5) in the properties panel, click "add tracker."
6) Place the tracker on a trackable location, and track a few frames by pressing the "track to end" button in the top of the viewer.
7) Export a transform (match-move) node in the tracker properties panel.
8) Double click the new transform (match-move) node to open the properties.
9) click the "2" button in the scale section of the transform properties to expand the width and height knobs on the scale knob.
10) hover over the scale height knob.

Result: scale height is scaling with the width instead of the height.

Workaround
Right click the knob, click "edit expression" and change the w to h to set it to scale with height.
