System.Windows.Forms.Tests.Text.FontMetrics.Font_MeasureText

Issue description

System.Windows.Forms.Tests.Text.FontMetrics.Font_MeasureText test fails with following exception and call stack in debug mode. Need to be investigated further before enabling it back. It seems runtime has assertion check on refcount that is bailing out in debug builds.

We observed this specifically on arm64 build but might have been happening on X86/64 as well.

Process terminated. Assertion Failed
