Method Draw has it fixed and this worked on my old branch. Replace the code in the default case:

https://github.com/methodofaction/Method-Draw/blob/de8eb4c6954e3dd1b71e06cdcece41f13d80d891/editor/src/svgutils.js#L494

    if(elname === 'use') {
      ret = groupBBFix(selected, true);
    }
    
    if(elname === 'use') {
      if(!ret) ret = selected.getBBox();
      //if(!svgedit.browser.isWebkit()) {
      //  var bb = {};
      //  bb.width = ret.width;
      //  bb.height = ret.height;
      //  bb.x = ret.x + parseFloat(selected.getAttribute('x')||0);
      //  bb.y = ret.y + parseFloat(selected.getAttribute('y')||0);
      //  ret = bb;
      //}
    } else if(~visElems_arr.indexOf(elname)) {
      try { ret = selected.getBBox();} 
      catch(e) { 
        // Check if element is child of a foreignObject
        var fo = $(selected).closest("foreignObject");
        if(fo.length) {
          try {
            ret = fo[0].getBBox();
          } catch(e) {
            ret = null;
          }
        } else {
          ret = null;
        }
      }
