Summary: /dialogue does not correctly respect "rawtext" arguments

Affects currently Live Content: No (but is limiting future content)

Impact: Limited functionality in dialogues, difficult to workaround

Repro Steps:

Please find a .mctemplate file attached with a test case for this bug. Press the buttons in-game to repro. Or run the following commands manually:

1. Run /function say_1, observe that rawtext works correctly with "selector".
2. In survival mode, run /function test_1. Observe that the raw text does not work correctly with "selector".
3. Run /function say_2, observe that rawtext works correctly.
4. In survival mode, run /function test_2. Observe that the raw text does not work correctly with "selector" and "score".

I have spoken with Fanny Vadillo Herrera, who asked the EDU team about this. Apparently, the text is resolving client-side, and have subsequently asked us to file this bug.

Observed Results:

✅ Chat text populates these selectors correctly. 

❌ NPC Dialogue does not populate these selectors correctly.

Only string literal {"text":"foobar"} appear to work with the "with" args.
 
Expected Results:

The dialogue 

Screenshots/Videos attached: Yes
