[re-fixed]WordPress "Preview Post" popup doesn't go to right page on first click of "Preview Post"
Normally, in WordPress, when one hits the "Preview Post" link while editing a post, a popup is spawned (or if you've previously hit Preview Post" and haven't closed the popup, it reuses the existing popup tab with the browsing context name* of "wp-preview-[postID]") at the url [color=#0044ff][site]/wp-admin/post.php[/color] . The popup usually then gets redirected to [color=#0044ff][post's public path]?preview=true&preview_id=[postID]&preview_nonce=[someNonce][/color] . However, I've recently been having the slight annoyance, only when using Vivaldi, that the first time I click the "Preview Post" button, instead of redirecting to the preview, the popup tab's address bar says [color=#0044ff][site]/wp-admin/post.php[/color], the popup tab waits blankly for a few seconds, then gets redirected to [color=#0044ff][site]/wp-admin/edit.php[/color] (the WP backend's list of posts). If I don't close the popup tab, and hit "Preview Post" again in the post editing tab, the reused popup tab then promptly gets correctly navigated to a post preview. If I close the preview popup tab, then hit "Preview Post", the several-second pause and wrong redirection happens all over again. It seems like the process of creating a new tab causes some sort of slowdown in completing the HTTPS negotiation to access [color=#0044ff][site]/wp-admin/post.php[/color], and I'm guessing the slowness causes some sort of timeout on the server that makes the server give up and just default to sending me to [color=#0044ff][site]/wp-admin/edit.php[/color], instead of [color=#0044ff][post's public path]?preview=true&preview_id=[postID]&preview_nonce=[someNonce][/color] .
Excellent, Snapshot 1.0.403.17 solves this!
Specifically, "VB-12256 POST to new window results in second GET request to same URL"
So that's what was happening. Thank you for the fix.
Ack, this is now happening again in 1.1.443.3 . :(
Edit #1: The latest team blog entry notes it (VB-16295) and says a fix will arrive in the next snapshot for it.
Edit #2: Fixed in 1.1.453.36
