This is a bug, because it works in strict CommonMark.
Here you can try how it works, an example with the CommonMark Strict option set. Obsidian seems to have a problem with documents that are CommonMark strict and don’t use any extensions.
As for the CommonMark Spec , there are links specified in ch. 6.2, for example as
[link](/uri)
The URI itself is specified in the RFC3986 standard, and cross-references are specified in Section 4.4 Same-Document Reference.
