Description
I get no "end" placeholder when using macros. Is this working as intended?
Problem
Here is an example:
When I expand the printl snippet I get no tabstop at all. Pressing tab will just insert tabs. Compare this to the exapned "OK" where a tab will place my cursor at the end.
Expected
Pressing tab will place my cursor at the end for macros

Research direction
Start by reproducing the macro expansion described in the issue, comparing the printl snippet with the expanded OK snippet and their Tab behavior. Trace the snippet expansion and placeholder handling from the relevant rust-analyzer entry point; done means macros provide an end tabstop so pressing Tab moves the cursor to the end.
