Breakpoint messing up playable timeline, just me?

I'm using playable timelines through out a scene to control certain game objects, while other are being controlled either via animator or script. In validating some of the data, I add breakpoints to kick over to the debugger and step through. When I do this, it seems like the editor is not pausing properly when switching to the debugger (MonoDevelop or VisualStudio/Code) so when I exit the debugger, the timeline jumps to some time in the middle, missing some of the event blocks.

Is anyone else seeing this or have I borked my project in some unknown way?
