Automatic image loading bypass with background-image: image-set

[ganthern]

Code such as this:

<table>
  <tbody>
    <tr>
      <td style="background-size:cover; background-position:center; background-repeat:no-repeat; background-image: -webkit-image-set(url('https://tutanota.com/resources/images/stock/code-security-lock-stock.webp') 1x, url('https://tutanota.com/resources/images/stock/code-security-lock-stock.webp') 2x);" background="https://tutanota.com/resources/images/stock/code-security-lock-stock.webp" align="center"></td>
    </tr>
  </tbody>
</table>

triggers loading (at least in Chrome 110.0.5481.100)
