Hi. When reading wiki pages with long titles e.g. https://ru.wikipedia.org/wiki/%D0%9E%D0%B1%D1%81%D1%83%D0%B6%D0%B4%D0%B5%D0%BD%D0%B8%D0%B5_%D1%88%D0%B0%D0%B1%D0%BB%D0%BE%D0%BD%D0%B0:%D0%98%D0%BD%D1%82%D0%B5%D1%80%D0%B0%D0%BA%D1%82%D0%B8%D0%B2%D0%BD%D0%B0%D1%8F_%D1%81%D1%85%D0%B5%D0%BC%D0%B0_%D0%9C%D0%BE%D1%81%D0%BA%D0%BE%D0%B2%D1%81%D0%BA%D0%BE%D0%B3%D0%BE_%D0%BC%D0%B5%D1%82%D1%80%D0%BE%D0%BF%D0%BE%D0%BB%D0%B8%D1%82%D0%B5%D0%BD%D0%B0/%D0%BF%D0%B5%D1%81%D0%BE%D1%87%D0%BD%D0%B8%D1%86%D0%B0/data.json, TOC is opened on the opposite direction from the needed, and it destroys the page layout.

|         TOC---------+

<-----------> expected page width
<---------------------> real page width

e.g.

• Open some page.
• Hide Main menu, Tools Menu, TOC.
• Close the page.
• Open some page with TOC.
• Expected: The page width is the same as the window width.
• Got: The page gets much smaller font, because there is a large grey area where the TOC is hidden.
• If one scrolls the page down, changing the TOC button location, the problem disappears.

For example, on LTR pages clicking on TOC rolls it down and right, and because the button is on the right side of the page, most of the TOC is out of the page. It should be mirrored, to open down and left, inside the page.

Other information (browser name/version, screenshots, etc.): I couldn't upload the Samsung Internet video here, it has more than 4MB, so it's on there instead for 30 days, hope it's enough time.

TODO

• Fix bug
• Add Pixel regression test so this doesn't happen again

QA Steps

Environment: Beta
On any page with a long title (i.e one that spans two or more lines) ensure that the TOC button is to the left of the title, and the language button is to the right of the title.
