I'm not sure if this is a WordPress or CKEditor issue, but previous to updating to the latest version of WordPress and CKEditor, when I saved a post/page the text editor would be displayed in the "mode" (html or visual) that it was last saved.
Now, if I save a post or page in html mode, the text editor for all other posts and pages open in html mode. Same thing if I save a post/page in visual mode.
This is a huge issue because some of my posts/pages use shortcodes that only work in either html OR visual mode.
Why has this changed from the way it use to work when each post/page would open in the mode that it was last saved in? Has anyone else experienced this issue?
