Bug#535780: libwebkit: webkit's JS returns localized CSS properties

Package: libwebkit-1.0-2
Version: 1.1.10-2
Severity: normal
File: libwebkit

The CSS properties returned by the style member of a DOM object is localized.
If e.g. you have set a height of '1.2em' for an object, comparing the object's 
height against '1.2em' will fail on some locales (seen in fr_FR) as the
property returns '1,2em' (with a comma), the localized version of '1.2em'.

In english locales there's of course no problem, but the behaviour is different
depending on the locale.

I have seen this in both Epiphany-webkit and Midori.

How to reproduce?
1) Write a small JavaScript function, like this for example:
   // reduce/increase height of an element
   // -> el is an DOM node
   function toggle_folding(el) {
     var folded_height = '1.2em';
     if (el.style.height == folded_height) {
       el.style.height = '';
     } else {
       el.style.height = folded_height;
2) Use it somewhere, like that:
       <title>WebKit JS test</title>
       <script type="text/javascript">
         function toggle_folding(el) {
           var folded_height = '1.2em';
           if (el.style.height == folded_height) {
             el.style.height = '';
           } else {
             el.style.height = folded_height;
       <style type="text/css">
         /* just to ensure the visibility of the folding effect */
         .foldable { overflow: hidden }
       <p class="foldable" onclick="toggle_folding(this);">
         Click me!<br/>
   The text should be shown/hidden when clicking on it.
3) See that it works properly with Gecko or with WebKit using with an English
   locale, but fail with WebKit useing a French locale: the text is hidden but,
   never shown again.
   To see why, simply show the value of el.style.height, wich is '1,2em'
   instead of the expected '1.2em'.
