[JIRAALIGN-1569] Edit Icon for the Title is missing on work items (MacOS only)

Issue Summary

On MacOS systems, the Edit icon for the title (which is usually a tiny pencil) is missing or misrepresented. In its place a tiny empty square, a tiny square with 01F589 code inside or a stacked line. Clicking on these "alternate" icons activates the edit functionality, so it's not completely broken. Just cosmetic at this point.

Steps to Reproduce

• By using a MacOS platform...

1. Browse to any grid page
2. Open any work item slide-out
3. Notice the missing pencil replaced by other icon

Expected Results

• We should see a tiny pencil denoting the Edit functionality.

Actual Results

There's either a tiny empty square, a tiny square with UNICODE 01F589 code inside or a stacked line instead of a pencil:

Workaround

Currently there is no known workaround for this behavior. A workaround will be added here when available.
