This is to be expected. A vendor can't sit and wait around forever on stuff.
The reality is many of the orders placed will fall of the manufacturers' lists via a 90 day timeline also.
It happened last panic also. After 90-120 days, the vendor gets contacted by the MFG, and they say "Are you still wanting to have this order on hold?"
Often, the answer is 'Let's stuff it and start over.'
This is how they will clear a 2 year backlog in 6 months. Just like last time.
