What happened/what you expected to happen?

What happened?

I deployed 2 workflows that has the same mutex the 2nd one wasn't visible in the UI till the 1st one finished

What is expected to happen?

The 2nd one used to be shown in the UI with the yellow mark saying it's pending and waiting for the mutex
