Missing Text, if clipping in any object is present

[jnvoigt]

If clip-path with a value that is not "none" is present it will clip the Content from any Text-Element. We want to use salamander to render charts from a weblibrary for generating charts.

How it should look

How it looks rendered with salamander

Sample:

<svg version="1.1"  xmlns="http://www.w3.org/2000/svg" width="350" height="100">
    <defs>
        <clipPath id="clipping">
            <rect x="0" y="0" width="508" height="299" fill="none"></rect>
        </clipPath>
    </defs>
    <g clip-path="url(#clipping)">
        <path fill="rgb(124,181,236)" fill-opacity="0.5"
              d="M 27 14.5 A 22.5 22.5 0 1 1 37 34 Z" stroke="#7cb5ec"
              stroke-width="1" ></path>
    </g>
    <text x="100" text-anchor="middle"  style="color:#333333;font-size:18px;fill:#333333;" y="24">
        <tspan>Missing Text</tspan>
    </text>
</svg>
