Hover information not working with UFCS

[exoticus]

writeln(format("Hello World %s", b));

This is the output produced by hovering the above non UFC line, it works and hover info shown for format and writeln as expected

However in case of this, only hover info shows for writeln but not for format

writeln("Hello World %s".format(b));

with the following output

limitation of DCD, however I think for goto definition and hover it might be possible to cheat around this a little bit

Autocompletion does not work in this case either.
