Are delayed skill effects represented in SimFF?

e.g. The Disembowel debuff is applied on the target a few moments after Disembowel's animation lock ends. If you use an off-GCD right after Disembowel's animation lock, your off-GCD won't get buffed by Disembowel.

Same thing for B4B. The reason why we can get a 9-GCD B4B with higher GCD recast times (e.g. 2.47s) is because the buff is added close to the end of B4B's animation lock, rather than immediately after B4B is used.
