Detailed tabs info in variant browser is not cleared while a new query is in process

[pamag]

Describe the bug

When filtering variants (sample variant browser or variant browser), after a filter is selected and while the data is being retrieved, the detailed tabs of the last selected variant is still on display.

Expected behavior

The info in the tabs should be cleared as it is oone in the grid. The same "waiting" animation of the grid could be displayed here.
