setAttribute doesn't work in inline_editable=true

[lerni]

With 4.2.1 $ElementBlahField->setAttribute('placeholder', $placeholdertext); just shows if inline_editable=false.

This will probably be a bug with something in admin, but I don't have time to investigate now.

Sounds very related to silverstripe/silverstripe-framework#9124

I have no idea of the cause, so I can't say anything sensible on that. But I can confirm this issue exists. I tried to get a dependant dropdown (sheadawson/silverstripe-dependentdropdownfield) to work inside an elemental form and the setAttributes are missing. I can't get any setAttributes to show on Elemental formfields

This issue seems to still be prevalent.

Temporary workaround (eg for placeholder attribute):
$field->setSchemaData(['attributes' => ['placeholder' => 'My placeholder value']]);
