And I get the same in daily mail. Thank you.

@IKhitron Can you make a screenshot, where you append ?uselang=en to URL, to make it readable to the most developers? Thanks.

I don't think there will be important differences, but here you are:

ok, thanks. In general it makes the screenshot for people like me better readable, because I normally don't read from the right to the left side ;).

Is the linked page a Flow board or regular wikitext page?

It seems that the template is parsed twice, because if I test with {{תב|תב}} as the section name (the Hebrew equivalent of {{tl|tl}}) I get this:

and I can reproduce that on localhost by creating a section with == {{tl|tl}} == and pinging a user in that section.

Change 284119 had a related patch set uploaded (by Catrope):
Use plaintextParams() for snippets and sections

Use plaintextParams() for snippets and sections

Checked in betalabs - for templates in section titles on wikitext based pages.

A template in the section title (e.g. == {{tl|tl}} == was used) does not mess up the layout anymore or display any errors.

In a notification, there is small part of section title code gets exposed - i.e. == .

Since there is general inconsistency in displaying transclusions as plain text between Flow board topic titles and wikitext pages section titles, the issue was filed as {T133319: Transclusions in section titles on wikitext pages not displayed as plain text in Notifications}.
