rust-analyzer breaks tab completion on VSCode

rust-analyzer version: 0.3.1443-standalone

rustc version: rustc 1.67.1 (d5a82bbd2 2023-02-07)

relevant settings:
"rust-analyzer.completion.autoimport.enable": false,
"rust-analyzer.completion.callable.snippets": "none",
"rust-analyzer.completion.autoself.enable": false

I use intellisense's tab completion, which allows me to cycle through completions by pressing tab until the proper completion shows up, at which point I can continue typing. This prevents the editor from erroneously substituting completions when I've finished with a line and want to move on to the next. It essentially makes it so that I can trust that the enter key will always insert a newline so that I can type without worrying whether or not the enter key will do the thing that my brain expects it to do.

Completions offered by rust-analyzer break tab completion.
In one case, I press tab, the first completion is substituted (with parenthesis or brackets that I didn't ask for and can't disable) and subsequent presses of the tab key only insert spaces according to my indentation setting.
In the other case, I press tab, the first completion is substituted (without those pesky auto-parenthesis/brackets), and subsequent presses of the tab key do nothing as VSCode fights to keep the cursor in place until I continue typing and rust-analyzer destroys the suggestions queue.

This has effectively disabled the use of completions in my rust workflow, and now a language I was really excited to learn is an absolute pain to do anything in.

MWE:

• cargo new hello
• open hello/src/main.rs in VSCode
• set "editor.tabCompletion": "on" in settings.json
• type prin and press tab twice, as if you were trying to get to println!
• watch helplessly as you end up with print!( )
• type a variable name that is the same as the beginning of another i.e. bean vs. bean_can
• watch helplessly as bean never turns into bean_can no matter how many times you press tab
  • Note: this also pollutes the undo history!

Please let me know if there's anything else I can provide.

Reproduce the issue in cargo new hello using hello/src/main.rs, editor.tabCompletion set to on, and the listed rust-analyzer completion settings. Start by tracing how rust-analyzer completions interact with VSCode IntelliSense tab completion for prin and bean; done means repeated Tab presses cycle through suggestions without inserting unwanted text, spaces, or undo-history pollution.
