Currently WebKit (and Blink) have some behavior where <param>s with name="movie", "src", "data", "code", or "url" can be used in place of the surrounding <object>'s data="" attribute. (WebKit appears to only use "data", "movie", and "src".) In Blink, we measured in the wild and found that 0.00002% of these cases successfully resolved to a PDF resource. (The only type of plugin supported by <object> these days.) All other cases did not resolve successfully to a resource, probably because the resource was something like Flash which we don't load. So, we are planning to remove this behavior in Blink. You can follow our progress in https://bugs.chromium.org/p/chromium/issues/detail?id=1315717 . Once this behavior is removed, the <param> element becomes a no-op, and pretty much all of its code can be deleted. 1862713 1 webkit-bug-importer 2022-04-19 13:56:17 -0700 <rdar://problem/91983957> 2002219 2 annevk 2023-12-29 04:20:04 -0800 Pull request: https://github.com/WebKit/WebKit/pull/22267 2003378 3 ews-feeder 2024-01-06 09:32:13 -0800 Committed 272734@main (acfd1f38e4e7): <https://commits.webkit.org/272734@main> Reviewed commits have been landed.
