Resize Drilldown section on Board pages

The option to resize the Drill down pane is not present in Board pages

It would be required to resize to look at list members or formulas in more detail. Currently the view appears as below, where list members are truncated

It would be great to have the ability to resize the pane

Resizing is possible in the Worksheet page (screenshot below of extended Drill down pane)
