ID 498359 - Filtering by group in resolution parameter dropdown shows duplicate resolutions if names are the same

Problem summary
Custom render resolutions defined in a resolutions XML file and loaded as part of KATANA_RESOURCES have a groupName property that allows the resolution to be part of a resolution group:

<format width="2048"    height="2048"    pixelAspect="1.0"    name="square_2k"    groupName="square"/>

Each node with a resolution field has a dropdown menu that can filter based on the groupName:

​

However, if there are multiple resolutions with the same ​name property value, the resolutions are duplicated when filtering by groupName.

Customer reported version
katana.4.0v5

Customer reported platform
windows11

Steps to reproduce

1) Duplicate the last resolution in KATANA_ROOT/plugins/Resources/Core/Resolutions/FoundryResolutions.xml
2) Change the duplicate resolution groupName value to "CinemaScope" so that both are in different groups.
For example, the last few lines should look like:

...
        <format width="2048" height="2048" pixelAspect="1.0" name="square_2K" groupName="square"/>
        <format width="2048" height="2048" pixelAspect="1.0" name="square_2K" groupName="CinemaScope"/>
    </formats>
</stormXML>

3) Start Katana
4) Create a RenderSettings node
5) In the resolution parameter, filter based on the "CinemaScope" group.

Expected behavior
"square_2k" should be listed once.

Actual behavior
"square_2k" is listed twice, showing a duplicate.

Workaround
Have a unique name property value for each custom resolution.
