Can't upload file via HTML form using <calcite-input> component ("Failed to set the 'value' property on 'HTMLInputElement'")

I'm receiving the console error DOMException: Failed to set the 'value' property on 'HTMLInputElement': This input element accepts a filename, which may only be programmatically set to the empty string. when trying to upload a file using the <calcite-input> Calcite Design Component. However, no issues when using the normal <input> HTML element with the same attributes.

        <calcite-input type="file" name="calcite_input_file" accept=".xlsx"></calcite-input> <!-- throws error in console, file not sent in request -->
        <input type="file" name="input_file" accept=".xlsx" /> <!-- no errors, file sent in request -->
        <button form="test-form" type="submit">Submit</button>
    </form>

Tried switching from Calcite Design Components v 2.7.0 to 2.8.0 but issue persists. Can just use the normal <input> HTML element and add my own styling to match the Calcite Design Components look, but would like to avoid that extra work :D hoping I'm just missing a required attribute for <calcite-input> file uploads or setting something up wrong.
