Issue description

This is a regression by #89389.

As a compensation for allowing Discrete and Continuous blending, the Dominant mode does not reset to the default value for Deterministic blending when Discrete track could take precedence. This is expected behavior, but the detected cases are too much.

In other words, the problem is that even when there is no Discrete track, it does not reset to the Default value, thereby abandoning the role of the Deterministic blending.

At least if there is a Reset track and it has a Continuous track, it works as intended, so it could be a documentation issue. Because without a Reset track, it is not possible to set an exact default value, so Deterministic blending cannot be used effectively.

However, from a usability standpoint, there should be consistent behavior when there is no Reset track, rather than a default that breaks the blend when a float value track is added and there is no Reset track.

Steps to reproduce

Adjust blend amount rapidly
