When updating embedded objects during our post layout checks, check for certain style changes
that may result in the plugin needing to be restarted.
* html/HTMLPlugInImageElement.h:
Add m_plugInDimensionsSpecified field to keep track of whether or not dimensions on the plugin’s renderer have been specified.
* html/HTMLPlugInImageElement.cpp:
(WebCore::HTMLPlugInImageElement::HTMLPlugInImageElement):
Initialize m_plugInDimensionsSpecified.
(WebCore::isSmallerThanTinySizingThreshold):
Refactoring, move check for whether or not plugin is smaller than the tiny plugin size threshold to this method.
(WebCore::HTMLPlugInImageElement::isTopLevelFullPage):
Refactoring, move check for whether or not plugin is top level full page to this method.
(WebCore::HTMLPlugInImageElement::checkSnapshotStatus):
Use refactored checks here as well to determine whether or not we need to restart the snapshotted plugin.
(WebCore::HTMLPlugInImageElement::subframeLoaderWillCreatePlugIn): Use refactored checks.
If plugin dimensions were specified, set m_plugInDimensionsSpecified to true.
