Area: AppKit Summary: When noncontiguous layout is disabled and -[NSFontManager fontPanel:] is called with "create = true", then the text view will fail to update itself properly when writing text. Steps to Reproduce: - disable noncontiguous layout on the text view - create the fontPanel early on (e.g. during applicationDidFinishLaunching) - enter text into the last line of the text view - prepend this last line with new lines by hitting enter, moving it down Expected Results: - the last line of text would draw 1 line further down with each press of the Enter key Actual Results: - the last line of text disappears for a split second, then reappears (in the next drawing pass?) at the expected location Version/Build: Xcode Version 9.2 (9C40b) macOS 10.13.2 (17C205)
