Why is bokeh FileInput limited to single selection

Is there a technical reason behind the fact that bokeh’s FileInput-widget is limited to a single selection?
As far as I know HTML5 and JS have the option to set a property
multiple="multiple".
However, in
bokeh/bokehjs/src/lib/models/widgets/file_input.ts (branch: master)
I find in line 19:
this.dialogEl.multiple = false

I can only guess (according to my TS/JS competence) that this is hard coding the single file selection limitation. Other frameworks, like dash allow for setting the “multiple” property in Python.

I need the user to upload up to 50 Files for the analysis of a single measurement, this limitation is a show-stopper for that application.

FileInput is a relatively new widget, and my guess here is that it’s just the very bare minimum implementation.
Feel free to create a feature request on the [Bokeh GitHub issues page].(Issues · bokeh/bokeh · GitHub)

my guess here is that it’s just the very bare minimum implementation.

This is exactly correct. Happy to discuss potential improvements on the tracker (especially with anyone who can help collaborate to make an implementation be ready faster).

I tried to amend the widget over the weekend but am stuck
here.
Maybe, you can help (over there) ?
