Selecting a value in DropdownField makes the field jump upward

[robbieaverill]

Version: 4.3.x-dev

With tractorcow/silverstripe-fluent 4.2.x-dev

• Go to locales
• Add a new locale
• Choose a value from the Locale dropdown
• Notice the field jumps upwards

This is affecting all chosen dropdowns by the look of it

Note this only appears to happen for Chrome. The latest version of Firefox is fine for me.

Solved by #681.

I can still reproduce this in 4.3.x-dev in some cases, for example in Security:

• Create a new member
• Tab through the fields
• Once you pass the Interface Language dropdown, notice the behaviour

[robbieaverill]

Still occurring in 4.3.2

[maxime-rainville]

Not seeing it on 4.x with Firefox.

[robbieaverill]

I should've been more specific, sorry. It's occurring for me in 4.3.2 on Chrome 72/MacOS Mojave

Issue still occurs in 4.3.
To reproduce the issue, you need to Keyboard 'Tab in' to the field and then 'Tab Out' of it.

[maxime-rainville]

I see it now in Chrome. Firefox is unaffected

Also present in 4.4.0-rc1
