title: Angular/Firefox: Missing Text arround a Path if URL-parameters in place
body: <p>I have a problems with Text on a SVG-path in combination with Firefox.
  Think it is a bug.</p>
  <p>Using Firefox 78.15, Angular 13.0.2, Debian 10.11 and Kernel 4.19.</p>
  <pre><code>import { Component, VERSION } from '@angular/core';
  
  @Component({
    selector: 'app-root',
    template: `
   Version={{ver.full}}
   &lt;hr/&gt;
   &lt;svg xmlns=&quot;http://www.w3.org/2000/svg&quot; xmlns:xlink=&quot;http://www.w3.org/1999/xlink&quot; height=&quot;300&quot; width=&quot;300&quot;&gt;
          &lt;path id=&quot;p1&quot; fill=&quot;transparent&quot; stroke=&quot;blue&quot; d=&quot;M 100 100 A 100 100 0 0 0 200 200&quot; stroke=&quot;blue&quot;/&gt;
          &lt;text font-family=&quot;Verdana&quot; font-size=&quot;20&quot; fill=&quot;green&quot; text-anchor=&quot;middle&quot;&gt;
              &lt;textPath startOffset=&quot;50%&quot; xlink:href=&quot;#p1&quot;&gt;Hello there!&lt;/textPath&gt;
          &lt;/text&gt;
      &lt;/svg&gt;
  
    `
  })
  export class AppComponent {
  
    ver = VERSION;
  }
  </code></pre>
  <p>It is about the text &quot;Hello there!&quot; arround the path.</p>
  <ul>
  <li><p>Chromium (90.0.x) =&gt; OK</p>
  </li>
  <li><p>Firefox with simple localhost:4200 =&gt; OK</p>
  </li>
  <li><p>Firefox with a URL-parameter (e.g. localhost:4200?x=3) =&gt; <strong>Text is missing!</strong></p>
  </li>
  </ul>
  <p>Why is that? How can I get my path in FF with a URL-parameter?</p>
