System.Drawing.PointConverter cannot convert values with leading white-space

[enyim]

Description

We have WinForms projects on .NET Framework that we are migrating to .NET 10+.

We've found that InitializeComponent throws on .NET 10:

System.ArgumentException :  is not a valid value for Int32. (Parameter 'value')
  ----> System.IndexOutOfRangeException : Index was outside the bounds of the array.

at System.ComponentModel.BaseNumberConverter.ConvertFrom(ITypeDescriptorContext context, CultureInfo culture, Object value)
   at System.Drawing.PointConverter.ConvertFrom(ITypeDescriptorContext context, CultureInfo culture, Object value)
   at System.Resources.Extensions.DeserializingResourceReader.DeserializeObject(Int32 typeIndex)
   at System.Resources.Extensions.DeserializingResourceReader._LoadObjectV2(Int32 pos, ResourceTypeCode& typeCode)
   at System.Resources.Extensions.DeserializingResourceReader.LoadObjectV2(Int32 pos, ResourceTypeCode& typeCode)
[...]

This was traced back to having Points in the .resx files with leading white-space, e.g. 2, 200. This works find on .NET Framework.

Reproduction Steps

foreach (var s in new[] { "1,200", " 2, 200", " 3 , 200" })
{
    Console.WriteLine(new System.Drawing.PointConverter().ConvertFrom(s));
}

Expected behavior

Values with leading white-space can be converted.

All target frameworks (4.8, 10, 11) should print

{X=1,Y=200}
{X=2,Y=200}
{X=3,Y=200}

Actual behavior

Exception on 10 and 11:

System.ArgumentException
  HResult=0x80070057
  Message= is not a valid value for Int32. (Parameter 'value')
  Source=System.ComponentModel.TypeConverter
  StackTrace:
   at System.ComponentModel.BaseNumberConverter.ConvertFrom(ITypeDescriptorContext context, CultureInfo culture, Object value)
   at System.Drawing.PointConverter.ConvertFrom(ITypeDescriptorContext context, CultureInfo culture, Object value)
   at Program.<Main>$(String[] args) in C:\slb\PointConverterTest\PointConverterTest\Program.cs:line 3

  This exception was originally thrown at this call stack:
    System.ComponentModel.BaseNumberConverter.ConvertFrom(System.ComponentModel.ITypeDescriptorContext, System.Globalization.CultureInfo, object)

Inner Exception 1:
IndexOutOfRangeException: Index was outside the bounds of the array.

Regression?

Yes, works on 4.8

Known Workarounds

NA

Configuration

10.x, 11.x (various versions), x64, Windows
