It's because of the TocTree extension, which adds floating to table of contents. It has special clauses for body.rtl, which can probably removed to let CSSJanus handle them automatically.

What about simply removing the extension, which has no aesthetic value at all anyway?

anyway?

I think it makes sense.

At the old Wikivoyage we could not test the extension for RTL languages. But the TOC behavior is realized only by CSS statements. I will look for additional styles.

I tested today better style sheet rules at he.wikivoyage:
(see http://he.wikivoyage.org/wiki/%D7%9E%D7%A9%D7%AA%D7%9E%D7%A9:RolandUnger/common.css)

/* Switching body.rtl properties off by setting to defaults */

body.rtl #toc .tocUl, body.ltr #toc .tocUl {
padding-left: 2em;
}

body.rtl .toggleNode, body.ltr .toggleNode {
left: -2em;
}

body.rtl #toc.tocFloat, body.ltr #toc.tocFloat {
float: left;
margin: 0 2em 1em 0;
}

/* New rules */

body.rtl.sitedir-rtl #toc.tocFloat {
float: right;
margin: 0 0 1em 2em;
}

After this, it was working well (most of the rules starting with body.rtl should be removed). This means only changing /toctree/modules/ext.toctree.css is necessary. Unfortunately I do not know how to make the corrections.

Changing the last option in [1] to false by default would fix the problem, though.

This is defined in CommonSettings.php…

    if ( $wmgUseTocTree ) {
            require_once( "$IP/extensions/TocTree/TocTree.php" );
	    $wgDefaultUserOptions['toc-floated'] = true;
    }

…as well as in InitialiseSettings.php:

    'wmgUseTocTree' => array(
	    'default' => false,
            'wikivoyage' => true,
    ),

However, I am not exactly sure what is the purpose of this extension. Of course, it provides the wiki with the tree option in their TOC, but do we actually need it at all?

The default properties for the Table of Contents properties can be changed to be switched off. Normally we proposed to have them switched off (This is the extension's default).

// default user options [from TocTree.php]
$wgDefaultUserOptions['toc-floated'] = false;
$wgDefaultUserOptions['toc-expand'] = false;

But the strong English community wanted to switch 'toc-floated' on. And all language branches must have the same default values (I think so). If you like to change it please discuss this problem with the English community.

Does this extension seriously add two preferences? Please just disable it on he.voy....

So I can see three ways out of this problem:

1. Disable the extension on he.wikivoyage;
2. Set $wgDefaultUserOptions['toc-floated'] = false on he.wikivoyage;
3. Commit a change to TocTree/modules/ext.toctree.css.

Option 3 is preffered here (fix it if it's broken, not just disable it).

@Roland: To fix that, you'd only need to install git & create an account on our Gerrit instance; there are some good instructions at:

• https://www.mediawiki.org/wiki/Gerrit/Tutorial

Or, if this is too much hassle for you, just submit a patch here and I'll commit it.

I removed the RTL-specific rules in this commit:
https://gerrit.wikimedia.org/r/#/c/61051/

It seems like CSSJanus does the right thing without them.

Css change has been merged. Perhaps reedy can decide whether or not to deploy the configuration change.

Is Amirs fix sufficient? Is it still needed/wanted? I will merge it if it is still needed/wanted.

According to my testing it is sufficient and needed.

(This is RESOLVED FIXED; Amir's patch should do the trick even without the config change.)
