Hi,
I'm using Dash with the following configuration:

dash-core-components==1.5.0
dash-html-components==1.0.1
dash-renderer==1.2.0

The issue is that html.ObjectEl() does not accept the data keyword but only a "data-*" wildcard

Indeed the following python code is raising an exception:

html.ObjectEl("your browser doesn’t support the object tag", data= "/a_link")

Exception:

TypeError: Unexpected keyword argument 'data'
Allowed arguments: accessKey, aria-*, children, className, contentEditable, contextMenu, data-*, dir, draggable, form, height, hidden, id, key, lang, loading_state, n_clicks, n_clicks_timestamp, name, role, spellCheck, style, tabIndex, title, type, useMap, width

Instead the expected behaviour should be the following HTML:

<object data="/a_link"> Your browser doesn’t support the object tag. </object>

calling the constructor with the wildcard works, but the produced HTML is different from the expected one:

html.ObjectEl("your browser doesn’t support the object tag", **{'data-test': "/a_link"})

return the HTML:

<object data-test="/a_link"> Your browser doesn’t support the object tag. </object>

                      The issue is that html.ObjectEl() does not accept the data keyword but only a "data-*" wildcard
                      Indeed the following python code is raising an exception:
                      html.ObjectEl("your browser doesn’t support the object tag", data= "/a_link")

                      Exception:
                      TypeError: Unexpected keyword argument 'data'
Allowed arguments: accessKey, aria-*, children, className, contentEditable, contextMenu, data-*, dir, draggable, form, height, hidden, id, key, lang, loading_state, n_clicks, n_clicks_timestamp, name, role, spellCheck, style, tabIndex, title, type, useMap, width

                      Instead the expected behaviour should be the following HTML:
                      <object data="/a_link"> Your browser doesn’t support the object tag. </object>

                      calling the constructor with the wildcard works, but the produced HTML is different from the expected one:
                      html.ObjectEl("your browser doesn’t support the object tag", **{'data-test': "/a_link"})

                      return the HTML:
