Bug 165753 – Wrong whitespace position in wrapped rtl

• Status: NEW
• Component: HTML Editing

[Adrian Heine]

Given a monospace textarea with a width of 6 characters with the following content:

>>>><<<<< (order)
012387654 (storage position)
Say ا ب ج

Firefox wraps like this:

 >>>><<  (order)
|012354| (storage position)
|Say  ا|

 <<<     (order)
|876   | (storage position)
|ب ج   |

Webkit wraps like this:

 >>>><<  (order)
|012345| (storage position)
|Say ا |

 <<<     (order)
|876   | (storage position)
|ب ج   |

I argue that Webkit's behaviour is wrong, since 4 and 5 are part of an rtl span and thus their horizontal order should be reversed content order.

I confirmed this in Epiphany with Webkit 2.14.2 and Chromium 55.
