Error "Slider was already initilized" somehow causes panel to log out

[itWilllBeOk]

Not sure if this is a rangeslider issue, but here goes:
after using the "insert link" function on a textarea field in the panel, an Error is thrown:
Uncaught Error: Slider was already initialized.
After that the panel immediately redirects to the login page.

When I remove the the rangeslider field from the page, the redirect doesn't happen.

I'm using Kirby 2.3.0, range slider 1.1.2. [edited: said 1.0.0 at first]

I can replicate the redirect on Win7, Chrome 50.0.2661.102 m / iOS 9.3.1, Chrome and Safari.
On Win7, FF 42.0, the error is thrown, but no redirect.
