Outline view: Support nested sections in R scripts for if / else nested braces

[seanthimons]

Not sure if this issue thread (#3822) has also fixed this or missed it, but when using if else statements with braces, section headers do not appear in the outline. Is there a way to force this behavior/ work around it, or is this expected behavior?

We had a lot of discussion of this in posit-dev/ark#867, and I will admit that I don't think we nailed the behavior in terms of how people use this in the real world.

@lionel- can you share workarounds that may be an option in a case like this?

The discussion in 867 was about a slightly different topic.

This looks like a bug to me, IIUC we collect outline element across blocks in function calls (e.g. test_that("", { ... }), but not across if and other constructs like for.
