Bug: Explorer does not respect negated .gitignore rule

[yatki]

• VSCode Version: Version 1.31.1
• OS Version: Majove 10.14.3

Steps to Reproduce:

1. Create the following files:

• /test/example/ignored.js
• /test/.gitkeep

2. Add the following rules to .gitignore

test/*
!test/.gitkeep

In the explorer .gitkeep file is grayed out even though git recognises it.

Does this issue occur when all extensions are disabled?: Yes/No
Yes

Just wanted to report this issue.

The changes in the file will be reported in the git tab but it will be greyed out as well. On the explorer tab, there would be a letter M indicating the change but still greyed out.

This issue is related: #38112. According to this comment it is caused by a bug in git check-ignore.
