.find(':first-child') vs .children(':first') in 1.3rc2

.find(':first-child') vs .children(':first') in 1.3rc2


Hey,
I've seen different behavior with these two functions in my
application after switching from 1.2.6 to 1.3rc2. I haven't been able
to come up with a test case, but I think it's related to append,
prepend,before and after (which is what I use before doing
calling .find())
Anyway, if anybody else has run into this and knows the explanation I
would really appreciate it. If you have been running into problems and
your application uses something like:
$('.myClass').find(':first-child')
use this instead:
$('.myClass').children(':first')
