Support replacing multiple custom template tags in one output path.

[TimothyBJacobs]

Fixes #15567

Description

Instead of returning after the first template match, continue looping and just update the path variable.

How has this been tested?

I've tested the change in my project and it works as expected.

I really have no idea how to unit test this.

Code looks good. Would you be able to add a unit test to capture what's being fixed?

[TimothyBJacobs]

Cool! I'd like to add a unit test, but I'm not really sure what the path forward is for something like this. I could combine it into the existing test? Or should I create a whole new fixture for multiple template tags?

[aduth]

@TimothyBJacobs If it's simple enough to include it in the existing test, that would be fine, as long as it provides sufficient coverage to both the base functionality and this specific fixed behavior (I think it should be).

[aduth]

I added a simple test case which verifies the fix (fails in master) in b456b3b.

Thanks for the fix!
