Click State Only Sticks on a Tap + Drag

First, I adore your plugin and have been using it for years. I’ve asked questions here a couple times since 2015, so as always thank you in advance for the support.

Please see the issue on my site (on mobile specifically!)

For whatever reason, buttons automatically re-collapse on-click, UNLESS they are tapped and the screen is dragged a bit while holding down the tap. Then, the “default” state is reversed, and a tap only makes it open-shut / shut-open starting with the other action.

I have no idea what could be causing this. Each button element has the following collapse-o-matic attributes:

classes: collapseomatic noarrow colomat-visited
rel: button-highlander

And then the content within is of course classed as “collapseomatic_content”

Thanks for any advice! The desired behavior is that a tap on a button opens the content without any issues, and this stays open until the original button is tapped again (basically, what you’d expect ^^)
