It's the follow-up ticket for T190283: CX2: Prevent publishing translations with too much unmodified content.
(1) When no MT option is used, the warning nevertheless appears along with the blank issues summary card.
- Start translation and do not use any MT options - set 'Do not use machine translation" as default.
- Click on 'Add translation' for several paragraphs/sections, but do not add anything - so the sections are blank.
- Try to 'Publish' - the warning appears: "Your translation cannot be published because it contains too much unmodified machine-translated text".
The same warning will be for 'Use source article' option:
Multiple Console errors are displayed:
Uncaught TypeError: Cannot read property 'id' of undefined at CXIssueTrackingTool.mw.cx.tools.IssueTrackingTool.focusCurrentElement (<anonymous>:906:40) at CXIssueTrackingTool.mw.cx.tools.IssueTrackingTool.onViewDetails (<anonymous>:905:725) at OoUiButtonWidget.oo.EventEmitter.emit (<anonymous>:64:486) at OoUiButtonWidget.OO.ui.mixin.ButtonElement.onClick (load.php?debug=false&lang=en&modules=ext.visualEditor.core|jquery%2Coojs-ui-core&skin=vector&version=1a1pe1w:981) at HTMLAnchorElement.dispatch (load.php?debug=false&lang=en&modules=ext.visualEditor.core|jquery%2Coojs-ui-core&skin=vector&version=1a1pe1w:875) at HTMLAnchorElement.elemData.handle (load.php?debug=false&lang=en&modules=ext.visualEditor.core|jquery%2Coojs-ui-core&skin=vector&version=1a1pe1w:872)
(2) The threshold in cx2 for "too much unmodified content" seems to be below 50% - the article cannot be published.
