Comment 1 for bug 1735310

I'm seeing this on 3.3 using Chrome on a MacBook Pro.

My recent fix for lp1538678 gives the unsaved data prompt consistently, however I'm encountering a similar pattern as described above. The first attempt if done while the 008 field is selected will remove it, and prompt to leave the page. If I have any field below if selected when pressing Shift+F8, it will disappear and reappear with different data. When the 008 field is gone, sometimes when pressing Shift+F8, absolutely nothing will happen. My guess is that the MARC Edit UI is fighting over the regular Evergreen UI for priority over the Shift+F8 shortcut - Retrieving the last record(as defined in the default keyset) vs. Adding/Removing 008(hardcoded in staff/cat/marcedit.js).
