Tabulator: selectable="checkbox" results in auto-selection upon editing

[lermana]

A pn.Tabulator created with selectable="checkbox" results in the following condition:

• if someone clicks in to edit a cell, that cell's row is automatically selected

I think the expectation is that the selection and editing are decoupled, i.e. someone could edit a cell without having to select it.

Panel version 0.12.1.

Thanks @lermana! Let's consider this as a bug and fix it in 0.12.5.
