(Looking at the screenshot, it may be that the names that are longer than one line get aligned to the left, but it may be just a coincidence. In any case, this shouldn't be the thing that sets the alignment.)

Given that the content is from the English Wikipedia, it makes sense to make all the titles aligned to the left.

Should it be true for the inverse - locale=Eng, wikipedia lang=Hebrew?

Phone locale is Eng and Wikipedia lang is Hebrew: articles' titles are displayed left-aligned:

2. Also, there is a question with History and Saved pages - when some of Saved or visited articles are in RTL language, their titles alignment is displayed based on the phone locale not on the articles' content language.

The latest build 2.0.101-alpha-2015-05-05 - when the wiki lang is switched to Hebrew:

The specific bug of misaligned titles(too much white space) seems to be fixed.

More discussion is needed and follow-up task(s) will be filed.

If we need signoff on the alignment of the titles along one single scan line, then the title for this task must be edited.
@kristenlans @Dbrant - could you please do that and file a separate ticket for follow-up tasks?

I'm merging this task into the broader task where we'll improve overall consistency of all our list items, which will include RTL considerations.
