- Edit a page in VisualEditor that contains invisible templates, e.g. https://en.wikipedia.org/wiki/Gladys_Cromwell (at the very top, above the infobox)
- Observe a broken-image icon:
This seems to be because ve.ce.minImgDataUri contains a too-aggressively minimized transparent GIF, which Safari has sometime-recently decided it cannot parse.
ve.ce.minImgDataUri = 'data:image/gif;base64,R0lGODlhAQABAAAAACH5BAEKAAEALAAAAAABAAEAAAICTAEAOw==';
This applies to Safari on desktop and mobile. Chrome and Firefox both cope with this image fine.
