ADC synchronization to TRGO2 and TIM break

On STM32 F7 I'm using ADC injected conversions triggered by TIM1 TRGO2 signal (OC5 rising).

In case TIM1 break2 is triggered what should happen to ADC injected conversions? Will break2 disable all PWM outputs including OC5 Ref thus stopping ADC trigger?

If yes this is a limitation when doing motor control based on ADC End Of Conversion interrupt, because in case of a break2 (due to some external fault e.g. some overcurrent) the control will not be called anymore.
