Problems:
HTML's native <button> tag doesn't support flex styling in all browsers,
causing layout bugs. And buttons or links created by "createDOMElement"
(without an accessibility role) do not have the correct props.
Solution:
The "button" role is rendered to a "div[role=button]" that is focusable
and responds to the same keyboard events as a native button. A native
button can still be rendered using "createDOMElement".
Make "createDOMProps" aware of the component context to ensure style
resets and other props are correctly applied when an accessibility role
is not defined.
Additionally:
This patch also adds a new "label" role to support accessible forms.
It maps to a native label element.
Close#241
Problem:
The content of style sheets was being set as a child of 'style', which
causes React to escape the content. This meant that the pointer-events
selectors were broken (">" became ">") and pointer-events were
disabled for the entire server-rendered document.
Solution:
Use 'dangerouslySetInnerHTML' to avoid the CSS text being escaped.
Fix#546
When rendered on the server, images now include the 'src' and will be
downloaded by the browser rather than waiting for the client-side JS to
initiate image loading.
Fix#543
Include modifier keys in the 'nativeEvent'. This allows keyboard
shortcuts such as "Shift+Enter" to be implemented for submiting text
input content when the modality is keyboard + mouse rather than touch.
The previous attempt at a fix (88ddeca0c6)
didn't account for 'View' handling the 'flexBasis' reset (as it used to
with 'flexShrink'). This patch moves flex style resolution into the DOM
style resolver.
Fix#426
Using requestAnimationFrame while registering styles/classes slows down
iOS/Mobile Webkit. By removing it, it's possible that we add a little
bit of overhead, slowing down current cycles, but should be mostly
unnoticed.
Fix#517
This changes the return value of 'getApplication' so that the
application element and stylesheets are all available as React elements.
Also changes StyleSheet's 'renderToString' to 'getStyleSheets'.
