Event: Stop shimming focusin & focusout events
Latest versions of all browsers now implement focusin & focusout natively and they all converged on a common event order so it doesn't make much sense for us to normalize it to a different order anymore. Note that it means we no longer guarantee that focusin fires before focus and focusout before blur. Fixes gh-4300 Closes gh-4362

@ -92,8 +92,7 @@ Some example modules that can be excluded are:
|
||||
- **effects**: The `.animate()` method and its shorthands such as `.slideUp()` or `.hide("slow")`.
|
||||
- **event**: The `.on()` and `.off()` methods and all event functionality. Also removes `event/alias`.
|
||||
- **event/alias**: All event attaching/triggering shorthands like `.click()` or `.mouseover()`.
|
||||
- **event/focusin**: Cross-browser support for the focusin and focusout events.
|
||||
- **event/trigger**: The `.trigger()` and `.triggerHandler()` methods. Used by **alias** and **focusin** modules.
|
||||
- **event/trigger**: The `.trigger()` and `.triggerHandler()` methods. Used by the **alias** module.
|
||||
- **offset**: The `.offset()`, `.position()`, `.offsetParent()`, `.scrollLeft()`, and `.scrollTop()` methods.
|
||||
- **wrap**: The `.wrap()`, `.wrapAll()`, `.wrapInner()`, and `.unwrap()` methods.
|
||||
- **core/ready**: Exclude the ready module if you place your scripts at the end of the body. Any ready callbacks bound with `jQuery()` will simply be called immediately. However, `jQuery(document).ready()` will not be a function and `.on("ready", ...)` or similar will not be triggered.
