This fixes a bug that was introduced in Select2 4.0.0 and only
partially fixed in Select2 4.0.6-rc.0 where the `title` attribute
that is set on the selection container (or individual selections,
for a multiple select) is not cleared when the text/title of the
option is not set. In most cases, users no longer see this issue
because the `text` property of most data objects is set, so the
`title` attribute will always be cleared correctly. There was a bug
for cases where the `text` property was not set, or where the `text`
property was set to an empty string, that resulted in the `title`
attribute persisting with the incorrect value.
We have fixed this issue by always removing the `title` attribute
from the selection (or not adding it in the first place, for a
multiple select) when the `text` and `title` properties of the data
object are empty or not present.
This also adds in a series of tests to ensure the `title` attribute
is set properly in a variety of cases, building upon the ones that
already existed.
Fixes#3895
These tests should fail because a selection can be removed even
though the container is disabled. This is because the only thing
preventing selections from being removed was the CSS which hid the
remove buttons when the container was disabled.
As jQuery 1.7.2 is the lowest version of jQuery supported by Select2,
it makes sense to run the tests on it. For the most part, we can
assume that the newer versions of Select2 are backwards compatible
enough such that this isn't an issue.
The recommended version of jQuery to use is the latest though, which
is why the jQuery file is only included in the tests.
This revealed a few issues with our data fallbacks and `.append`
functionality that was introduced in jQuery 1.8.
The search box previously displayed a clear icon on the far right
side in webkit-based browsers, specifically Chrome and Safari. This
hides the clear icon in those browsers, and also fixes a slight
sizing issue, so it should no longer be displayed.
This also disables autocorrect, autocompleted, as well as a few
other automatic search corrections on the field, so mobile devices
should have a better experience.

This is needed to escape any bad markup that is passed through
user-entered data. Users can prevent their markup from being
escaped by using a no-op `escapeMarkup` function.
