Bug 1973726 - Set DOM file path for webkitRelativePath. r=sefeng,geckoview-reviewers,webidl,smaug,ohall
Actually, there is no way to set webkitRelativePath from JavaScript.
Since GeckoView's folder picker handles virtual file data, we need to
set relative path from JavaScript directly.
A content URI of System storage document provider only allow file data
access from file/folder picker, so there is no way to test it on
geckoivew-junit.
Also, after landing bug 1591640, GVE always crash when using folder
picker. So this includes a fix for it.
