This is in response to #3207 to address concerns regarding third-party
scripts and browser plugins potentially altering DOM nodes within
document.body, causing problems with reconciliation.
Closes#3211.
Console is undefined in earlier versions of IE when it is not open. This causes an uncaught exception, and breaks applications in these versions of IE when attempting to warn when the console is closed.
Admittedly, console will usually be open when testing in development, but still React should not break the application when it is not.
These are the only places that seems to be including environment specific
variables in the message format.
By ensuring that they're static, we make it easier to group logs by
format. I also ensure that I keep each addendum separate so that they can
be filtered/grouped separately.
This is a new version of cloneWithProps but this one is moving out of
add-ons. Unlike cloneWithProps, this one doesn't have special logic for
style, className and children.
This one also preserves the original ref. This is critical when upgrading
from a mutative pattern where a child might have a ref on it.
It also preserves context, which is similar to how context would work when
it is parent based. It also ensures that we're compatible with the old
mutative pattern which makes updates easier.
Without this, transitioning from `<div onClick={null} />` to `<div />` triggered `willDeleteListener` to delete the `click` handler which caused problems; now, we only call `putListener` and `deleteListener` when we have an actual listener.
I now also clean up the `onClickListeners` map upon deletion and don't double-listen when updating the event listener.
