Muradin's spyglass proc bug

[ssdh233]

Describe the bug
It should be stacked every time when player deals damage, including dots(corruption, curse of agony), channel spell(drain soul, drain life), and instant spells(shadowbolt, haunt). But in wowsim, it seems it only get stacked on instant spells

To Reproduce
Steps to reproduce the behavior:

1. Go to wowsim, select affliction warlock
2. Choose any gear with trinekt Muradin's spyglass[H]
3. Simulate on any situation which includes a 25% execution, and check Timeline
4. You will find "Cultivated Power" (the buff from this trinket) will only get 1 stack after 25% execution. And apparently it only get stacked on haunt.

Expected behavior
"Cultivated Power" should get stakced every time corrupton, curs of agony, unstable affliction and drain soul deals damage.
