Non-traditional or Matching in Javascript Regex?

Correct me if I'm wrong, but I believe the regular expression ({|}) would traditionally match either a { or a }. But when I have a string like this: "{hello i'm a string}" and I call this function: 

var album = $(song).data('album').replace(/({|})/, '', 'g');

Only the { is replaced, leaving the trailing }. What gives?

I believe the non-standard flags parameter is ignored if the first argument is a regexp object. According to the MDN:

To perform a global search and replace, either include the g switch in the 
regular expression or if the first parameter is a string, include g in the 
flags parameter.

For your example, the following works:

> "{hello}".replace(/({|})/g, '')
> "hello"
