Hyper on method call causes incorrect highlighting

[0racle]

Description of issue

When using the hyper » op to perform a method call, all subsequent method calls (which are normally un-highlighted/white) are highlighted incorrectly until a character appears that has a specific color.

Screenshot of the issue:

Above screenshot taken using the 256-color jellybeans color scheme.

Sample code:

# Blue methods after hyper method call
@arr.words».tc.join.split().comb».join.split[0];

# No issues seen on normal method call
@arr.words.join.split.join.comb.subst(1, 1).tclc;

@0racle Thanks for the report! I can see what you're saying; can you provide an example (both screenshot and code) of a chained method call that doesn't use » and thus highlights correctly?

I've updated the screenshot in the issue.

Here's what I'm seeing when I run vim -u NONE -c 'source syntax/perl6.vim' -c 'syntax on' -c 'setf perl6' example.pl:
