Inconsistent NormalizeNewLines formatting

[RJIntraffic]

Since migrating from the previous vscode extension I've had the same issue described in: #361

With this test file:

*** Test Cases ***
Test
    Embedded "args"


*** Keywords ***
Embedded "${args}"
    No Operation

And this robot.toml:

[tool.robocop.format]
configure = [
    "NormalizeNewLines.enabled=True",
]

When formatting the test file with the vscode extension multiple times. The file will cycle between the following states:

1. No change after the first format
2. An extra whitespace line is added before *** Keywords ***

*** Test Cases ***
Test
    Embedded "args"



*** Keywords ***
Embedded "${args}"
    No Operation

3. The file returns to original state
4. FIle doesn't change
   Repeat from 1

When formatting with robocop via the CLI this issue doesn't happen.
robocop format test.robot --config robot.toml
(Since it might be relevant, robocop also work as expected when disabling caching
robocop format test.robot --config robot.toml --no-cache)

It seems to have something to do with the NormalizeNewLines.section_lines and NormalizeNewLines.test_case_lines variables? When either of these variables is set to 0 this issue doesn't occur. However when both these variables are > 0 the formatting becomes inconsistent.

The RobotCode output doesn't seem to show anything:

executeRobotCode: c:\XXX\Python310\python.exe -u -X utf8 c:\XXX\.vscode\extensions\d-biehl.robotcode-2.5.1\bundled\tool\robotcode --format json --no-color --no-pager -dp . discover --read-from-stdin tests -I test.robot --suite Robottest.Test
executeRobotCode: exit code 0
