Accessing certain properties of a VML group element causes errors in Internet Explorer

[sorccu]

The VML group element has some properties that are not meant to be accessed. Accessing any of them will cause an error and invalidate all other properties of the element at the same time. This means that selectors such as jQuery’s $(‘:submit’) will fail because they access these properties.

The properties that cause errors are: type, opacity, chromakey, spt and forcedash.

The JavaScript typeof operator will return “unknown” (not “undefined”) for all these properties.

All other VML elements are OK with any existing or non-existing property.
