[patch] bugfix for Opera

[[email protected]…]

Today's changes broke Opera 8.50 completely. Opera defines some objects similar to IE or FF, but not all properties and methods are implemented.

Example:

if (document.selection) document.selection.clear();

This code breaks Opera because document.selection doesn't have clear() method. Opera's document.selection is a string. Its only method is createRange(). The correct code should check for methods before calling them:

if (document.selection && document.selection.clear) document.selection.clear();

The same goes for new SVG sniffing, which expects enabledPlugin to be defined.

The document.selection code is in a try-catch block so that should actually be fine without modification. I've applied your changes to hostenv_browser.js though.

Thanks very much for taking the time out to create these patches, it's very much appreciated!

I tested it and ... it doesn't work. try/catch is funny in Opera. You should apply the patch to html.js.
