VisualEditor: Parameter data doesn't always end up in the right parameter box in Firefox
Open, LowPublic

Description

Report from Jay8g about a bug that may be very hard to reproduce:

"After adding a parameter in the (advanced) template dialog, the focus briefly shifts to the previously added (edited) parameter before going to the one just added. This has led to me occasionally (about one in ten parameter additions) typing (generally just one character) in the wrong box"

"I would type something *immediately* after clicking the parameter button and it would only happen occasionally"

Jay's running Firefox 30 on Windows 7. I've been unable to reproduce this, but I probably haven't tried enough times or been fast enough. I've been wondering whether this might be easier to reproduce on an old, slow computer.

The issue is confirmed - it is most noticeable in FF35 on Windows. I've attached a screencast for FF35 on Mac - the problem is noticeable as "jumpiness" of parameters in Template dialog.

Important - to reproduce the bug, add parameter that will be placed after previously entered parameter, e.g. after parameter AA add parameter ZZ. Then you can see more clearly that the cursor will be placed momentarily into the previous field.
