Issue getting BPM from FL Studio through AudioPlayHead::currentPositionInfo

I’m testing my plugin in various DAWs and found that AudioPlayHead::currentPositionInfo.bpm just gives back 0.0 when running as an AU inside FL Studio. The VST3 version gets correct BPM, and both AU/VST3 get correct BPM in e.g. Ableton Live and Logic Pro X.

Is there a known issue with FL Studio?
