I’m not sure if it is intentional or not but the free bomb buff from the ‘Ranger’s Parting Gift’ talent on Ranger Veteran has infinite duration (until a bomb is thrown). This means that you can throw one free bomb even after ‘Disengage’ has ended. The talent description isn’t very clear as it states “thrown within the duration of the ability”:
Here is some evidence of the infinte duration in action:
As you can hopefully see ‘Disengage’ ends yet the free bomb buff persists and allows a free bomb to be thrown after (sorry if it’s not clear, 7 second gifs were not the best format for capturing this).
Again, this could be intentional in which case the talent description could be updated to be more clear. Personally I like it this way as it makes the talent a little bit more flexible (i.e. sometimes you need to use ‘Disengage’ in an emergency and don’t get the chance to throw a bomb, but this way makes up for that).
