- Open the Demos page
- Select Apex theme (WikimediaUI works correctly)
- Scroll down to the "TagMultiSelect" section
- Enter some tags into the first widget
- Open the "show code" and enter widget.setDisabled( true ) in the console there.
Either the "X" icons remain sized and positioned as they were before step 5, or they disappear entirely like in the WikimediaUI theme.
