Commented Unassigned: Lots of tests fails [9422]

Hi
When I clone the source (Git hash: 4cbcac89e85eb03c9cf31ad4162e729db69a596f) and run the tests 95 of the tests fails.
I have not analyzed all of them, just picked the first: AddingDataSet:
```
Test Name: AddingDataSet
Test FullName: ClosedXML_Tests.Examples.MiscTests.AddingDataSet
Test Source: c:\Git\closedxml\ClosedXML\ClosedXML\ClosedXML_Tests\Examples\MiscTests.cs : line 12
Test Outcome: Failed
Test Duration: 0:00:00.972

Result Message:
Actual file 'C:\Git\closedxml\ClosedXML\ClosedXML\ClosedXML_Tests\bin\Debug\Examples\Misc\AddingDataSet.xlsx' is different than the expected file 'Misc.AddingDataSet.xlsx'. The difference is: '/xl/styles.xml :NonEqual
/xl/worksheets/sheet.xml :NonEqual
/xl/worksheets/sheet2.xml :NonEqual
/xl/worksheets/sheet3.xml :NonEqual
'
Expected: True
But was: False
Result StackTrace:
at ClosedXML_Tests.TestHelper.RunTestExample[T](String filePartName) in c:\Git\closedxml\ClosedXML\ClosedXML\ClosedXML_Tests\TestHelper.cs:line 83
at ClosedXML_Tests.Examples.MiscTests.AddingDataSet() in c:\Git\closedxml\ClosedXML\ClosedXML\ClosedXML_Tests\Examples\MiscTests.cs:line 13
```

I unpacked the ClosedXML_Tests\bin\Debug\Examples\Misc\AddingDataSet.xlsx and ClosedXML_Tests\Resource\Examples\Misc\AddingDataSet.xlsx by renaming them to zip, unpacking and then comparing them.

In /xl/styles.xml applyNumberFormat="1" is in the Debug... and applyNumberFormat="0" in the Resource...
The same with applyAlignment="1" vs applyAlignment="0".

In /xl/worksheets/sheet.xml and /xl/worksheets/sheet2.xml and /xl/worksheets/sheet3.xml there is the same difference
<x:col min="4" max="4" width="9.4906250000000014" style="0" customWidth="1" /> in Debug... and
<x:col min="4" max="4" width="9.830625" style="0" customWidth="1" /> in Resource...

Any ideas what might be wrong?
I tried changing locale to both en-US and en-GB without success, but since there are no textual differences in the files I suppose that would not be the case anyway.
Seems something in the environment could be the issue. But what?
Framework/OS version? Screen resolution?

I attached the output from the test written to C:\Git\closedxml\ClosedXML\ClosedXML\ClosedXML_Tests\bin\Debug\Examples\Misc\AddingDataSet.xlsx
