I started emacs -Q and though I have the mode installed via
package.el, I did not want to setup package stuff, so I just
copied the code from here:

https://raw.githubusercontent.com/Malabarba/aggressive-indent-mode/master/aggressive-indent.el

Turns out with this latest version the problem is not reproducible.

I made a diff compared to my installed version and apparently the
new, working version adds the `after-change-functions` which you wanted
to remove among other things . (diff attached)

So the problem went away, because I upgraded to the latest version,
which is good, but I'm still wondering how the syntax parser got
confused because of indentation stuff.
