try/catch inside jQuery.style() has a negative impact on perf in Safari and Opera

[lrbabe]

To prevent IE from throwing errors when 'invalid' values are provided, the line of code that sets a value to style property has been wrapped by a try/catch (see #5509)

This has a highly negative impact on performance both in Safari5 and Opera11, as shown by this test:  http://jsperf.com/try-catch-impact-style#results

We could add a feature test to jQuery to detect when the browser throws an error for an invalid value and add it to jQuery.support.invalidStyle. We would then change the code in css.js to

jQuery.support.invalidStyle ?
    try { style[ name ] = value; } catch(e) {}:
    style[ name ] = value;

Oops, the try/catch is inside jQuery.style, not jQuery.fn.style

On the other hand, a patched jQuery performs even worse in Firefox and Opera and only slightly better in Chrome and Safari.  http://jsperf.com/jquery-style-try-catch-impact

It is probably better to leave it as is right now.

Closing as trying to avoid the try/catch makes situation even worse.
