Hi Team, Another clean-up similar to Blink, it was only WebKit specific and never supported by Internet Explorer and Firefox. Blink dropped it in 2014: Blink Commit - https://chromium.googlesource.com/chromium/blink/+/6439470ea6427ec3944b3a2865002c726e1b883e WebKit Source (example): https://searchfox.org/wubkat/source/Source/WebCore/html/HTMLFrameElementBase.cpp#169 & https://searchfox.org/wubkat/source/Source/WebCore/html/HTMLFrameElement.idl#40 Just wanted to raise it so we can track and when I get sometime, I can get my hands dirty to do PR. Thanks!
