1259604 - Confluence search textbox resets its horizontal scroll-position as you type (and after you type), keeping you from seeing what you're typing

Status: NEW

(Core :: Layout, defect)

Description

[Daniel Holbert [:dholbert]]

STR:
 1. Visit some Confluence instance, e.g.
      https://demo.stiltsoft.com/ (no login required)
   ...or:
      https://mana.mozilla.org (requires MoCo login)

 2. Type "This is my long search term", or some other longish search term into the box in the upper-right corner of the page.

ACTUAL RESULTS:
While you're typing, and when you're done typing, the textbox continually updates its autocomplete dropdown, and *with each update, the textbox's horizontal scroll position is reset to the beginning. So your cursor (where you're currently typing) gets continually clipped, and you can't really see the text that you're typing as you're typing it.

EXPECTED RESULTS: Textbox's scroll position shouldn't be continuously reset; it should follow your cursor and keep up with your typing.

Chrome 51 (dev edition) gives me EXPECTED RESULTS.
Firefox 48 (nightly) gives me ACTUAL RESULTS.

Note: in Chrome, the widget does reset its scroll position (as in Firefox) **if it loses focus**, e.g. if I click somewhere else on the page.

So our problem might be that the page thinks the widget is losing & regaining focus (and it resets the scroll position each time), or something like that.
