Rust-analyzer status bar disappears when the active opened file tab in VSCode is a non-Rust file

rust-analyzer version: v0.4.2270
rustc version: rustc 1.83.0 (90b35a623 2024-11-26)

editor or extension: VSCode 1.96.3 with rust-analyzer extension v0.4.2270

The r-a status bar disappears even when there are other tabs opened with Rust files on a Rust workspace.

I think it is better that the r-a status bar doesn't disappear if the server has been started (which is always the case even on non-Rust workspaces), so that the server can be easily stopped/restarted for the current window by clicking on the status bar.

This was a deliberate design decision to paper over the fact that rust-analyzer activated a little too eagerly in multi-language repositories, especially when few other language servers don't have a such a prominent visual status bar. It's the been source of many issues.

We expect that with #17537, we should be able to be more precise with regard to rust-analyzer activating. In the meantime, I think setting "rust-analyzer.statusBar.showStatusBar" to "always" should fix your immediate issue.
