Make mouse-2 yank in org headlines

Question

I use mouse-2 quite often for mouse-yank-primary. However, if I am at the start of an org-mode headline, instead of yanking from my cut buffer, it toggles the level of the headline. For example, if I have the cursor at the start of a level 1 headline(| used to represent cursor):

* |

Press mouse-2 and it becomes:

** |

...instead of yanking the text I want as the headline. Then if I press mouse-2 again, it becomes a level 1 headline again, and will keep toggling between the two on subsequent presses. How can I change this behavior to yank instead of changing the headline level? Normally I can figure these things out on my own, but I have had trouble in the past when it comes to changing the behavior of mouse buttons.

Update:

I tried describe-key before asking this question, and it seemed like mouse-2 should do what I want, but I just noticed at the bottom of the describe-key description for theup-event it says:

<mouse-2> at that spot runs the command (lambda (e) (interactive "e") (mouse-set-point e) (org-cycle)), which is an interactive Lisp function.

It is bound to <mouse-2>.

(anonymous E)

Not documented.

I assume this is what is causing my issue, but it doesn't seem clear to me where this is coming from.

A search for the binding delivers: org-bullets.el.

See the documentation of org-bullets-bullet-map. There you find:

Should this be undesirable, one can remove them with (setcdr org-bullets-bullet-map nil)

They propertize the bullets with this:

(put-text-property (match-beginning 0) (match-end 0)
                   'keymap org-bullets-bullet-map)`
