Help hover / completions no longer "sees through" smart pointer types implementing Deref (like Arc)

rust-analyzer version: 0.4.2283-standalone (a995319 2025-01-27)

rustc version: rustc 1.83.0 (90b35a623 2024-11-26)

editor or extension: VSCode

If you have a snippet of code like this

pub fn start(runtime: Arc<tokio::runtime::Runtime>) {
    runtime.block_on(async {})
}

then in the release version of RA if you hover over block_on() then you'll get a help popup, and if you type runtime. you'll get completions for Runtime. Neither of these are working in the current pre-release.

Here is a video showing the issue (slightly too big to upload straight to github, sorry):

I think this may be a duplicate of #19040, they mention they can't get underlying target completions when the type is a MutexGuard, and I've also seen an issue with that as well (that also used to work in the release version)

I think that this is #19059, which has been fixed in our newest release(2025-01-28) via #19061. Sorry for the inconveniences.
