1. open Android app
2. search for User talk:7&6=thirteen
3. pick first result
4. title appears with part of first <span> (but none of the second <span>)

title saved currently is {{DISPLAYTITLE:<span style="text-shadow:0px 0px 9px silver;"><span style="color: #060"><span style="display:none;">User talk:</span>7&6=thirteen</span></span>}} https://en.wikipedia.org/wiki/?oldid=1244870954

I was guessing there's some code splitting on first appearance of a colon in page title?

If I go from the broken talk page view to edit history via hamburger or from history on to a diff those pages are both fine. If I visit the talk page other ways like search first for user page and then go from there to talk via hamburger then display is fine. also if I open talk page in Firefox focus then "open in app" then the display is fine. got here via T353611: Diff link giving wrong diff when page title has symbols (&, =)
