Hi,
I am having an issue with kendo labels being marked as "orphaned form label" (label was not read by NVDA screen reader) when using the kendo editor with [iframe] set to false to have non-encapsulated style in the Editor.
The WAVE browser extension does show the "orphaned form label" alert for some of your controls (dropdowns, multiselect) but since you have the aria-label attribute NVDA reads the label text values for those controls.
However, I have noticed that no such aria attribute is added/updated when the [iframe] input of the Editor control is set to false.
I have checked this in your example stackblitz environment and it seems to reproduce the issue as well.
Regards,
