There is, I think, a strange behavior regarding setting morph sliders to their default.
Before CC3.4, double-clicking the label with a slider would return the value to the default from whatever value it was set to.
This is still the case in CC3.4 for sliders that range from 0 to 100. However, for sliders that range from -100 to 100, the behavior is peculiar.
If the slider is set to any value except +100, double-clicking the label resets the value to 0, as expected. However, if the value is at +100, double-clicking sets the value first to -100. Double-clicking it again resets it to 0.
When this was discovered, I reported the issue in FT as
#7733. Yesterday, I got an email that the issue was NOT considered a bug and it is now closed.
It may not be a bug, but it is certainly bizarre. I cannot thing of any case where this is useful. What do you think?
