Autofocus on HFR change triggers if HFR detection is turned off initially.

[x] Are all prerequisites that are mentioned inside the manual met?

Description

When you have autofocus on HFR turned on for a sequence, the autofocus will trigger if you turn on HFR detection in the middle of a sequence, presumably because “no HFR” and “0 HFR” are considered the same. Similarly, having HFR detection off will cause the HFR change autofocus trigger to not take effect because the HFR is not calculated.

Steps to Reproduce

• Turn HFR detection off in the Imaging tab
• Start a sequence with autofocus configured to trigger on HFR change
• Wait until at least one image is taken in the sequence
• Turn HFR detection on in the Imaging tab
• Autofocus should trigger after two subsequent images.

Expected behaviour

A sequence with autofocus trigger on HFR change should either force HFR detection on in the imaging pane, or turning on HFR detection should ignore points from before HFR detection is turned on.

With the next beta build the hfr calculation is enforced when the autofocus after hfr change is enabled.
