@RussKie I've offered a couple of ideas here:

I think it wood be helpful (to investigate further) to know inputs (parameters) and CallStack of extra Invalidated. So, for example this test:

control.Invalidated += (sender, e) => invalidatedCallCount++;

can be transform to something like:

control.Invalidated += (sender, e) =>
{
    Assert.True(++invalidatedCallCount <= expectedInvalidatedCallCount,
        $"Input: {rowHeadersWidthSizeMode}, {rowHeadersVisible}, {autoSize}, {value}");
};

What do you think?
