I've been looking for solution to this.
Is there a way to filter the file explorer that comes up to display specific file type?
Does setting the supportedFileTypes property have any effect?
This option still opens file explorer will all the files, only validates the file when file is selected.
Not a deal beaker but, if we can filter file explorer files in windows, this will help user one step.
The behavior is entirely browser-defined. If your users truly need this level of hand-holding local control, use Vision.
Check your html. I thought Perspective's supportedFileTypes mapped directly to that accept property.
Is there a way to force HTML?
How should I raise this as possible bug?
Via support ticket, officially. Otherwise you're just hoping somebody from the right team comes along and sees this post, agrees with overall sentiment, and feels compelled to open the issue.
I don't think it's a bug. The documentation doesn't promise what you're expecting.
Instead, create a feature request.
I created a feature request.
Thank you.
