Steps to trigger the unexpected behavior

When i run setPaintProperty on our vector tiles (running on our own tileservice, created with tippicanou) than it request some tiles again.

its happen for example when i switch between this two styles.

map.setPaintProperty("cableLayer", "line-color", "red")

map.setPaintProperty("cableLayer", "line-color", [

        "case",
        [
            "==",
                [
                    "get",
                    "type"
                ]
            ,
            "5"
        ],
        "#686868",
        "#686768"
    ]
)

but not when i run the same style again or this, without get

map.setPaintProperty("cableLayer", "line-color", [

        "case",
        [
            "==",
                [
                    "string", //<==========
                    "type"
                ]
            ,
            "5"
        ],
        "#686868",
        "#686768"
    ]
)

so i beleave its happend because of the get expression.

i tested it also on the default mapbox style but woudnt get this behaviour.

this is the source config

{
    "type": "vector",
    "promoteId": {
        "cable": "id"
    },
    "tiles": [
        "https://xxxxx.com/{z}/{x}/{y}?regionId=yyyyy&scenarioId=defaultScenario&year=2025"
    ],
    "bounds": [
        6.005877,
        51.617003,
        6.229508,
        51.791297
    ],
    "minzoom": 10,
    "maxzoom": 18
}
