First bug : I use the beta the "2017 wikitext editor" it's become my main editor. I activate the beta "Wikitext editor syntax highlighting". I try to desactivate the beta "Wikitext editor syntax highlighting", it's work for the usual vector editor. But, I cannot desactivate the beta "CodeMirror" when I use the "2017 wikitext editor". The "Wikitext editor syntax highlighting" isn't tick in the beta menu, but I still there in the edit window when I use the "2017 wikitext editor".
In the same time, I cannot use the "Wikitext editor syntax highlighting" without the "2017 wikitext editor". I try to desactivate just the "2017 wikitext editor", but It doesn't work until I desactivate also the "Wikitext editor syntax highlighting".
But, if the problem was just that, It will not be very funny.
Second bug : Because the combinaison of the "2017 wikitext editor" and the "Wikitext editor syntax highlighting" have a huge bug when I use them. (I'm on chrome, on chromebook (I don't think chromebook matters).
See : File:Bug Mise en forme du texte avec la syntaxe Wiki.png => The highligt text in the window editor isn't in the same line that the text I select. It's offset downwards relative to the text selection. So when I want to select a line for example to do to some editions (the usual business on a window edition ...), I need to select the previous line and calculate the offset to click in a non visible line. It's very very annoying... For me the combinaison of the two gadget is not usable at this moment.
