The PR #18911 removes global window.CodeMirror, now when input Enter in EasyMDE, there is an error (window.CodeMirror.Pass):

EasyMDE.js:80 Uncaught TypeError: Cannot read properties of undefined (reading 'Pass')
    at Enter (EasyMDE.js:80:34)
    at doHandleBinding (easymde.js:8129:14)

    at CodeMirror.onKeyDown (easymde.js:8219:19)
    at HTMLTextAreaElement.<anonymous> (easymde.js:4928:22)

This PR fixes the error.

Why not cm.Pass?

CodeMirror.Pass exists, while cm = CodeMirror(...); cm.Pass doesn't exist.

I have read through the EasyMDE and CodeMirror code, it's impossible to access CodeMirror.Xxx in Gitea now.

Fine I guess if the end result is the same.

It is the same. CodeMirror document said: the default command for Enter is newlineAndIndent.
