HUD goes blank outside pitch angle limits, but does not use same limits to return

[Machalot]

This may not be new in 2.7, but I just noticed it for the first time.  When the aircraft is pitched above or below a certain angle, the HUD goes blank.  However, it doesn't resume displaying when the pitch angle is back within the limits.  It seems to stay blank until the pitch angle gets close to zero.  Track attached.
