1025873 - Strange behavior after wrapping elements into a dropdown box

Status: RESOLVED WORKSFORME

(Firefox :: Translations, defect)

Description

[Bogdan Maris, Desktop Test Engineering]

Attachment: Screencast showing the issue

STR:
1. Start latest Nightly.
2. Change value of prefs 'browser.translation.detectLanguage' and 'browser.translation.ui.show' to 'true'.
3. Visit http://ru.wikipedia.org and hit Translate.
4. Set Firefox on half screen. Until a dropdown appears in the left of search field from webpage)

Expected result: All the necessary elements are hidden in a block.

Actual result: Elements are hidden in a dropdown block but the menubar containing those elements are jumping up and down.

Notes:
1. Screencast showing the issue attached.
2. Browser console:
"XUL box for hbox element contained an inline span child, forcing all its children to be wrapped in a block." 
highlighter.js - Line 584, Col 1:
    infobarContainer.appendChild(infobarPositioner);
- this warning appears when I open the Inspector.
3. The jumping only happens on Ubuntu, on Mac and Windows after the translation, the menu elements are not forced into a dropdown block at all (same warning in console though).

Sounds like an issue with the website. Maybe it's triggered by the fact that we are displaying a string that is longer/shorter than the original one?

I no longer reproduce.
