Toggle Bubble Guide can affect the wrong engine

I realize this is a minor issue because no one would use two warp engines in practice, but I had to report it for completeness after noticing it.

In the VAB, I placed both the big warp engine and the small one on the same craft at the same time (plus another mod's warp drive, ignore that). Toggling the bubble guide of the second one I placed (small) worked fine, but right clicking the other engine to toggle its bubble guide toggled the wrong engine's guide.

Before clicking, large engine's right click menu active:

After clicking, other engine's bubble disappears:

I assume there's a FindFirstOrDefault call or something equivalent rather than a direct binding to the part whose menu was clicked.
