[betalabs] Add link: switching to source editor results in persistent page re-loading
Closed, ResolvedPublic


  1. A user goes to Suggested link article and switches to the source editor.
  2. When the source editor finish loading - click to switch back to VE.

The page starts reloading and it goes indefinitely (see the gif below):

Not sure if the lines from the Console are relevant:

[Violation] 'requestAnimationFrame' handler took 56ms
load.php?lang=en&modules=jquery%2Coojs-ui-core%2Coojs-ui-widgets|jquery.ui&skin=vector&version=s8882:49 [Violation] 'setTimeout' handler took 448ms
[Violation] Forced reflow while executing JavaScript took 296ms
load.php?lang=en&modules=jquery%2Coojs-ui-core%2Coojs-ui-widgets|jquery.ui&skin=vector&version=s8882:49 [Violation] 'setTimeout' handler took 81ms
load.php?lang=en&modules=startup&only=scripts&raw=1&skin=vector:23 [Violation] 'requestIdleCallback' handler took 127ms

It seems to complain about these lines:

function getCombinedVersion(modules) {
                    var hashes = modules.reduce(function(result, module) {
                        return result + registry[module].version;
                    }, '');
                    return fnv132(hashes);

Note: Currently editor default setting in Preferences - "Remember my last editor". That means - just switching to the editor makes that editor "the last editor" used. If a newcomer switches to the source editor, the Suggestion mode will be lost. Since the VE dialog is suppressed, it might be even more difficult for users to figure out how to get back to the the Suggestion mode.

Also related, clicking on "View history" will take you back to Suggestions mode.

This seems to be caused by my changes to open edit mode via JS

			if ( suggestedEditSession.shouldOpenArticleInEditMode && $editLink.length ) {
				uri = new mw.Uri();
				if ( uri.query.section ) {
						uri.clone().extend( { section: uri.query.section } )
				$editLink[ 0 ].click();

When View History is clicked and suggestedEditSession is restored, shouldOpenArticleInEditMode is still true so this block is called again when it shouldn't be.
