Theming: overriding is broken for gif images

[VicDeo]

1. Enable theme-example
2. Enable notifications app
3. Set Mail Notifications in personal page to 'Notify about all events'
4. php occ notifications:generate -u boo --link http://home.org go home!

Expected

Mail notification has logo-email.gif from theme-example

Actual

Mail notification has logo-email.gif from core

GitMate.io thinks possibly related issues are #3209 (Theming), #13402 (... broken), #20484 (Orientation for shared images broken), #31134 (Theming broken after trying to enabling a second theme), and #23569 (Theming image path).

affected version ? stable10 or 10.0.8 ? @VicDeo

[VicDeo]

@PVince81 I got this with master and didn't test further. But I guess @ChrisEdS had the same with OC 10

[ChrisEdS]

Yes @VicDeo - I stumble upon this issue in 10.0.8

[VicDeo]

@PVince81 I'd like to start with this one for the next sprint
also it would include lib/private/URLGenerator.php refactoring for #31864

esimate: 1-1.5 md

[PVince81]

@VicDeo is the refactoring included in your estimate ? Or just the bits from #31864 required for the fix ?

[VicDeo]

@PVince81 yes, refactoring of lib/private/URLGenerator.php (just one class) is included into estimate as I suspect it to be the case
