How to reproduce
- Use Chrome 58
- Open a single page in HTML editor that has an image embedded
- Click on image
=> NOK: nothing happens, image not selected.
In the console some errors appear
The problem also applies to Vivaldi 1.9 which is based on the Chromium render engine.
The problem has been recognized by TinyMCE, there is no path around updating TinyMCE to fix the problem:
Instead of clicking the image one can drag a bit (klick-drag). This will select the image.
