Framemaker 2020 -- Bug 9622 now 1 year old and not fixed - Product default conditional tags

I would consider this a bug. The following conditions are for FrameMaker internal use only and shouldn't be available to the user. They are not displayed in the Condition Tags panel.

FM8_SYSTEM_HIDEELEMENT
FM8_TRACK_CHANGES_ADDED
FM8_TRACK_CHANGES_DELETED

I don't know anything about the PDF comment feature. Are there any cases where you would manually apply the conditions below to FrameMaker content? If not, they should be hidden as well.

FM_PDF_Comments_Highlight
FM_PDF_Comments_Underline

Here is the ExtendScript code I ran to write all of the condition formats in an active document to the Console panel:

#target framemaker

var doc, condfmt;

doc = app.ActiveDoc;
condFmt = doc.FirstCondFmtInDoc;
while (condFmt.ObjectValid () === 1) {
    Console (condFmt.Name);
    condFmt = condFmt.NextCondFmtInDoc;
}
