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].(https://github.com/bokeh/bokeh/issues)

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) ?
