Does a slow Avalon slave block the Lightweigh HPS-to-FPGA bridge?

We have multiple Avalon slave devices running off the Lightweight bridge on a Cyclone V. One device is fairly slow and has to do long block transfers (32 bit transfers at a time). The IP holds waitrequest active for most of the cycle releasing it just at the end so the next request can come in. I'm not clear - while each word is being transferred is the lightweight bridge able to service requests to other slaves while it's waiting for the slow slave to complete its transfer or will other accesses stall until the transfer completes?
