Reproduction steps

1. Open a test file from the test folder.
2. Click on the "Run In Terminal" link on a single specific test (not the one above the whole class definition.

In the terminal the issued command will be eg.:
"C:/Ruby33-x64/bin/ruby.exe bin/rails test s:/project_folder/test/models/geometry_m/geometry_test.rb:4"

This command runs every tests (not just in this file, but even in the entire project).

Additional information and trials:

1. Problem is independent of how the binary is invoked: "C:/Ruby33-x64/bin/ruby.exe bin/rails test ..." and "rails test..." produces the same result
2. If I use relative path to the file in terminal command, it works as expected: "C:/Ruby33-x64/bin/ruby.exe bin/rails test test/models/geometry_m/geometry_test.rb:4"
3. The same problem occures if I don't use "Run In Terminal" but "Run" link instead and also running form the Test Explorer
4. I searched a lot (in Ruby LSP's source code too) for any possible configuration of the test command arguments, but I couldn't find anything. Even couldn't locate when, how and where the command is built up.
