As a WWT user, I want the plus and minus symbols for RTL languages to stay on the left, so that common standards of plus/minus representation are maintained.
Background: When viewing a revision popup in an RTL language, the revision size difference shows the plus/minus sign to the right of the number. It should stay on the left, same as in LTR.
**Acceptance Criteria:**
* For RTL languages, display plus and minus symbols on the left (i.e., same as in LTR) in WWT
**Steps to reproduce problem:**
1. Go to https://en.wikipedia.org/wiki/Thornton-le-Beans_Chapel?uselang=he
2. Start WWT
3. Click the first word of the article
**Expected behavior:** Size difference should be: (+4,541)
**Observed behavior:** Size difference displays as: (4,541+)
**Environment:**
* WWT version:** 0.12.0.
**Visual Examples:**
