Inline Coverage from vitest is not shown

[motz-art]

Describe the bug

When I run the test in the repo, I do not see inline coverage in the editor. And in the Window output I see an error:
[error] Error loading coverage details Illegal argument: character must be non-negative.

Reproduction

1. Run the test from the repo https://github.com/motz-art/vscode-vitest-coverage-issue.git.
   Expected:
   Inline code coverage is shown in the editor.
   Actual:
   Only high level coverage info is shown but inline coverage info (code lines are not highlighted) is missing.
   At the same time Window output shows one error:
   Error loading coverage details Illegal argument: character must be non-negative

Note: When I change the test to call process(1); instead, then inline code coverage is shown properly:
