[yew-devel] [PATCH yew-widget-toolkit] improve keyboard navigation with fields in data tables

[Dominik Csapak]

when inside an input field in a data table, the intention was to focus
the next cell when pressing tab. This currently does not work correctly,
since 'cell_focus_next' tries to focus the next element next to the
already focused one, and that is not the cell itself but the field
inside.

Instead of trying to fix that, simply let the browser handle the focus
handling. This has the advantage that in table with multiple fields
(like we have in the PDM node list for remotes) we directly focus the
next input field instead of the next cell (which would need another
press of 'tab' to focus the input field).

The downside is that to focus the next cell (if it does not contain an
input), one has to "go out" of the field by pressing F2 and then
pressing tab.

Since in a data table with fields it is often more useful to navigate
between those instead of the table cells, i opted for this solution.

In addition, add a tabindex of '0' to the triggers, so they'll always be
able to be focused.
