Bug 8106 – REGRESSION (NativeTextField): New text fields don't scroll to the beginning when losing focus

• Status: VERIFIED
• Resolution: FIXED
• Component: Forms

New text fields don't scroll back to the beginning when they are unfocused.

To reproduce: enter long text in a text field, making it scroll to the right (to show the end of the text), then click outside the text field (to unfocus it).

Expected result: the text field should scroll to the left, showing the beginning of the text, when it's unfocused.

Actual result: the text field doesn't scroll back when it's unfocused.

I've got a fix for this one.

RTL fields should scroll all the way to the right. The patch made them scroll to the left :-\

I have to admit I even thought of that, but I wasn't sure how to code that correctly.

I think I have the code right to handle RTL correctly now, but only for the "blur" case, not for text fields that never had focus in the first place.

By the way, Firefox does not have this behavior for text fields. You could even consider this an anomaly of AppKit text fields. The reason they scroll to the beginning when they lose focus is that the base field has no scrolling capability, only the field editor does.

So I'm not entirely sure it was a good idea for me to have fixed this!

These are all text field regressions so they should all be P1.
