1425433 - select unintended click

Status: UNCONFIRMED

(Core :: Layout: Form Controls, defect, P3)

Description

[hendrik.behncke]

User Agent: Mozilla/5.0 (Macintosh; Intel Mac OS X 10.13; rv:57.0) Gecko/20100101 Firefox/57.0
Build ID: 20171206182557

Steps to reproduce:

1. Open the example on https://developer.mozilla.org/de/docs/Web/HTML/Element/select
2. Click and hold the mouse button on the select
3. Move the mouse a tiny bit and then release the mouse button

Now the current hovered value is selected and the dropdown closes.

This does also happen when repeating the steps with a 'natural' click behavior.


Actual results:

The current hovered value is selected unintended


Expected results:

The select dropdown should stay open until a second click is happening on the actual value to select it.

Some users may use it to quickly select without second click.

Comment 2

Yes, it should be possible to hold down the mouse button and select a value. 
But currently you have to be very precise with the mouse to open a select, because the smallest mouse movement will close the select immediately.

This has definitively changed in Firefox 57.

I can not see this effectively in Firefox 57 & 58, it seldom happens.
