Users are reporting problems with Safari and the Atto editor behaving strangely. Setting text as a heading causes either the file manager to open or turns the text into subscript. Setting a font color fails.
Here is a video that demonstrates the problem.
I can reproduce this problem but instead of opening the file manager, when I try to set a heading, I get subscript instead.
How to reproduce:
1. Open the editor.
2. Select text and try to set it as a Heading.
3. Select text and try to change the font color.
The user who reported the problem to us:
Operating System: Mac OS X
Browser: Safari 602.3.12
My own system:
Operating System: Mac OS X 10.11.5 (15F34)
Browser: Safari 9.1.1 (11601.6.17)
I will add that I can reproduce problems on the moodle demo site and in the clean theme of our own installation and I do not have any safari extensions installed.
