Describe the bug

Wrong colors on input borders when dropping Files with correct Filetype (obj / XLSX) setting on Edge always "red" for all input files and types. On Firefox only setting red border style for obj files.

Expected behavior

Show specified color in style_active attribute of input component

dcc.Upload(
    id=f"{id_str}-upload-data",
    children=html.Div(
        [
            "Drag und drop oder klicken um Datei für upload auszuwählen."
        ]
    ),
    style={
        "width": "100%",
        "height": "60px",
        "borderWidth": "2px",
        "borderStyle": "solid",
        "borderRadius": "5px",
        "borderColor": "var(--bs-primary-border-subtle)",
        "textAlign": "center",
    },
    multiple=False,
    accept=file_extension,
    className="align-content-center",
    style_active={
        "borderStyle": "solid",
        "borderColor": "var(--bs-success)",
    },
    style_reject={
        "borderStyle": "solid",
        "borderColor": "var(--bs-danger)",
    },
),

File type get set as "text/csv,application/vnd.ms-excel" for XLS inputs and .obj

Start with the dcc.Upload reproduction and its accept, style, style_active, and style_reject settings, then reproduce the drag-and-drop behavior in the reported Edge and Firefox versions. Done means valid .obj and XLS/XLSX drops show the active styling rather than the reject border, with invalid files still showing the reject styling.
