Running ktlintFormat twice deletes files

Steps to reproduce the bug

1. Use ktlint-gradle version 9.1.0 and ktlint version 0.35.0 with the following configuration:

ktlint {
    version = "0.35.0"
    debug = true
    verbose = true
    android = true
    outputToConsole = true
    outputColorName = "RED"
    enableExperimentalRules = false
}

1. Run ./gradlew ktlintFormat --continue once. (Then run git status, and observe that the auto-formatted files were modified)
2. Run ./gradlew ktlintFormat --continue a second time

Expected Behavior Running ./gradlew ktlintFormat --continue the second time should not making any additional changes. The previously modified files should still show up as modified in git status, and no files should be deleted.

Actual Behavior All the files that were previously marked as modified are now deleted (observed via git status).

I also tried the gradle integration recommended in https://github.com/pinterest/ktlint without plugins, and running the non-plugin ktlintFormat task multiple times did not delete any files. This makes me suspect that the bug is in ktlint-gradle.

Thank you for the report, I’ve successfully reproduced it 🤔

That is my plan I want to do tomorrow…
