[Bug] CustomStamps exports an invalid textColor in case of the default white text color

[uwohlfeil]

WebViewer version
10.9.0

The current behavior
When I export the custom stamps as json and import them again, stamps with the default font colour white lose their font colour.

The expected behavior
Exported stamps can be reimported without changes.

Steps to reproduce

Create to Stemps. One with the default white text color and one with another color:

The JSON looks like this.

[
  {
    "title": "Draft1",
    "subtitle": "[$currentUser] DD/MM/YYYY h:mm A",
    "color": "#4F9964",
    "id": "68a51049-d4c3-2212-ea4f-fe8e4ca6421c",
    "font": "Helvetica",
    "bold": true,
    "italic": false,
    "underline": false,
    "strikeout": false,
    "textColor": { "R": 255, "G": 255, "B": 255, "A": 1 }
  },
  {
    "title": "Draft",
    "subtitle": "[$currentUser] DD/MM/YYYY h:mm A",
    "color": "#2A85D0",
    "id": "06893209-4687-da3b-2713-a53f186d62b8",
    "font": "Helvetica",
    "bold": true,
    "italic": false,
    "underline": false,
    "strikeout": false,
    "textColor": "#ca9999"
  }
]

After I reimport the stamp, the white texted Stamp has an invisible text.

If I fix the textColor to #FFFFFF, the stamp is correct.

I think, the problem maybe located here:
