Describe the bug
Role of death with activated Bidirectional DSHOT and RPM Filter on SPRACINGH7EXTREME

To Reproduce
Bidirectional DSHOT was fixed with this issue betaflight#8836.
I updated to Build betaflight#1900 (28.09.2019 22:50:24) and activated rpm filter. Everything else is set to default. Sometimes it happens that the quad performs a role of death. (Log is attached LOG00008.zip)

Without activated bidir and rpm filter it works great with no issues.
