[BUGFIX] Show RecordList tooltip only on hover

The default trigger action defined by Bootstrap is "hover focus",
which keeps the tooltip active when the button is focused,
e.g when that button opens a popup on click.

Switch the trigger behavior to "hover" to hide the tooltip after clicking
a button.
