Expected Behavior

Upon calling obs_frontend_set_tbar_position API function, I expect the transition bar in studio mode to move to the specified point, and the transition should also proceed to the specified point.

Calling obs_frontend_get_tbar_position() should return X after calling obs_frontend_set_tbar_position(X)

Current Behavior

Upon calling obs_frontend_set_tbar_position the transition bar did not move at all. The transition did proceed to the specified point as expected.

Calling obs_frontend_get_tbar_position() did not return X after calling obs_frontend_set_tbar_position(X) and instead returned the same value it had prior to the set_tbar call.

Steps to Reproduce

1. Create a plugin
2. Call obs_frontend_set_tbar_position(512)

Anything else we should know?

I haven't done a full commit by commit bisect, but this API works as expected in 29.0.2 but not in 29.1.0-beta1. The only obvious change I could find is 8d4a0b3
