Wrong(?) order of http/2 requests to the same server that start at the same time

Wrong(?) order of http/2 requests to the same server that start at the same time
I've noticed that sometimes WPT waterfall shows requests in the order that does not seem to be the order in which the requests are issued by the browser.

For example here:

https://www.webpagetest.org/result/18110...view_step1

Item 2 in waterfall is HTTP/2 Stream: 7 (as you can see response comes last)
Item 3 in waterfall is HTTP/2 Stream: 3
Item 4 in waterfall is HTTP/2 Stream: 1 (as you can see it is the only one with DNS+TCP+TLS before)
Item 5 in waterfall is HTTP/2 Stream: 5

They all have the same request start time (coming from <link rel=preload>) and this is probably why -- AFAIU requests are sorted by start time, but if multiple start at the same time, they get wrongly shuffled.
