Yesterday appeared strange mass error in ru-Wikisource.
In **namespace Page** the edit field of proofreading pages is broken. Now it is replaced by the div 'CodeMirror', and 'div.prp-page-edit-body textarea' is disabled by `display: none`. The scan image must be to right from text, but it now below. The colontitul fields must be above and below text field, but now it below. And broken syntax highlighting.
This screenshot of a [[ https://ru.wikisource.org/w/index.php?title=%D0%A1%D1%82%D1%80%D0%B0%D0%BD%D0%B8%D1%86%D0%B0:%D0%9F%D0%BB%D0%B0%D1%82%D0%BE%D0%BD%D0%BE%D0%B2%D1%8B_%D1%80%D0%B0%D0%B7%D0%B3%D0%BE%D0%B2%D0%BE%D1%80%D1%8B_%D0%BE_%D0%B7%D0%B0%D0%BA%D0%BE%D0%BD%D0%B0%D1%85_(%D0%9F%D0%BB%D0%B0%D1%82%D0%BE%D0%BD,_%D0%9E%D0%B1%D0%BE%D0%BB%D0%B5%D0%BD%D1%81%D0%BA%D0%B8%D0%B9).pdf/144&action=edit | page ]].
Also, in the browser console is red error "Uncaught Error: Another textSelection API was already registered" with mention of the CodeMirror script.
**In Main namespace** the syntax highlighting of editor is broken too.
To example, all edit text shows as underlined and strange colored. Or all text colored strange blue color, if change only one letter of any word then color of all text changing, if after change other letter then color changed again to other color, and so on. In other time a page to edit there is no syntax highlighting, or only template on top edit text is colored.
I do not want any syntax highlighting!
Also, 'CodeMirror' conflict with gadget "[[ https://www.mediawiki.org/wiki/User:Remember_the_dot/Syntax_highlighter | SyntaxHighlighter ]]" (from user settings). So the edit page loading very long or freezes. And the browser tab overload 100% of CPU and make leaking memory.
Could you disable this function? I can't work with such color theme.
Perhaps, better will make gadget for it, somebody will be have ablility to enable/disable if wanted.
**Disabling work other gadgets.** To example, wikificator. As I understand, it because gadgets works with the edit field in certain div in html. But this extention creating other edit field and show it in browser. Also, I seems, other gadgets can not work with such text, because it has many styling of symbols.
Why is there no description of this feature? And the editors do not understand why the basic gadgets do not work.
I found this problem yesterday. Did not any changes scripts or Meta settings in our ru-Wikisource.
Appears if login to Wikisource, but not edititng as anonim. Perhaps this problem no in other interwikies, e.g. I did not found it in Suomi Wikisource, but no any gadgets there.
I did not changed my user settings. In Edit section on https://ru.wikisource.org/wiki/Служебная:Настройки#mw-prefsection-gadgets I have all enabled gadget, but not "DotsSyntaxHighlighter" on bottom (mentioned above) and 3 from top (url shorter).
I have all disabled on https://ru.wikisource.org/wiki/Служебная:Настройки#mw-prefsection-betafeatures.
