StaticResource Converter doesnt work inside DataTemplate

[DevDrake]

Describe the bug

Hi, I am having the same issue that was already fixed few years ago.
#1464 (#1464)
I simply created a window resources DataTemplatethat uses custom converter to convert enum to utilize as simple combobox enum picker.
Exactly the same code works when not in DataTemplateon the same view.

To Reproduce

simply use below in datatemplate. Standard pattern for conversing enum into choice picker.

<ComboBox ItemsSource="{Binding Path=MyEnumProperty, Converter={StaticResource EnumConverter}, Mode=OneTime}" DisplayMemberBinding="{Binding Description}" SelectedValueBinding="{Binding Value}" SelectedValue="{Binding Path=MyEnumProperty, Mode=TwoWay}"/>

Unlikely you have the same issue...

Please provide a minimum sample to reproduce.

Sidenote: why is the binding onetime explicitly? Oneway (default) should be enough, no?
