New linkify rule does not linkify URLs entirely when they have a preceding text token

[miteshashar]

Describe the bug

context

v2.2.0...v3.0.0#diff-06572a96a58dc510037d5efa622f9bec8519bc1beab13c9f251e97e657a9d4edR21-R23

When I provide this input:

http://example.org/foo._bar_-_baz This works

This doesnt http://example.org/foo._bar_-_baz

While this `does` http://example.org/foo._bar_-_baz, this doesnt http://example.org/foo._bar_-_baz and this **does** http://example.org/foo._bar_-_baz

This applies to _series of URLs too_ http://example.org/foo._bar_-_baz http://example.org/foo._bar_-_baz, these dont http://example.org/foo._bar_-_baz http://example.org/foo._bar_-_baz and these **do** http://example.org/foo._bar_-_baz http://example.org/foo._bar_-_baz

expectation
I expect all URLs to get linkified correctly and entirely.

bug
But instead the ones indicated in the provided input do not get linkified.

problem
This is a problem for people using URLs in their content, because they expect consistency in the output.

Reproduce the bug

The provided input content suffices to indicate the use cases where the bug occurs.
