When I try to upload a file to a table the top left cell is automatically selected. This also happens when other things happen. For example when changing Tabs (internal dash tabs).
This means that the screen will automatically move to that table when returning to the tab which makes it quite hard to use. It can be repliacted by taken the code from https://github.com/plotly/dash-recipes/blob/master/upload-data-to-table.py and just adding a second tab. The top right cell will always be selected.
Its like it has the autofocus Attribute (https://www.w3schools.com/tags/att_input_autofocus.asp)
Have tried it on different browsers and the issue still occurs as well as on different laptops.
Edit: Really weird but it works fine on Internet Explorer (which is slightly disturbing).
