All of the below properties or methods, when requested/called in JavaScript, will trigger the browser to synchronously calculate the style and layout*. This is also called reflow or layout thrashing, and is common performance bottleneck.
Generally, all APIs that synchronously provide layout metrics will trigger forced reflow / layout. Read on for additional cases and details.

| # Mac OS X webarchive is a binary format of a plist file. You can extract the contents manually: | |
| # 1. convert the plist file into XML by "plutil -convert xml1 file.webarchive" | |
| # 2. parse the resulted XML file by some XML parser | |
| # 3. decode "WebResourceData" by Base64.decode64(data) in each key | |
| # 4. save the decoded content into a file indicated by "WebResourceData" | |
| # Thankfully, the plist library can take care of annoying steps 2 and 3. | |
