Bad Safari extensions bug with context menus

from blog The Desolation of Blog, | ↗ original
This blog post is a heads-ups to Safari extension users, Safari extension developers, and hopefully the Safari extensions engineering team at Apple about a bad bug in Safari with extensions and context menus. The bug is that if you have a Safari extension enabled, and the Safari extension has a context menu item (as many extensions do), then opening a context menu on a link can sometimes cause the link to open, as if you had just clicked the link instead of control-clicking. This bug was introduced recently; my suspicion is that started with the software releases on March 24, which included Safari 13.1 for Mac. I have filed a report (FB7666007) in Apple's official bug reporting system. The following are steps to reproduce on the latest versions of Catalina and Mojave with Safari 13.1 installed. (The bug also occurs with Safari Technology Preview 104.)
