Double dash HTML error on iOS

Tell us what’s happening:

The system on iOS is automatically changing the dash so I had to create all comments like this in order to proceed ( <!- - , - -> ). Once I typed them in, I would remove the space so the interface would recognize this. The example below shows me using the technique I described on the first portion only. It corrects the double dash to “-—“ in the interface.

Thank you.
