Large amount of whitespace between rows on show2D

Description

If show2D goes onto two rows, there is a large amount of whitespace between the rows. I have experienced this in different notebooks.

An example:

Example code:

show2D([recon.array[67,50:90,50:90], recon_thickness.array[67,50:90,50:90], recon_attenuation.array[67,50:90,50:90], recon_filter.array[67,50:90,50:90], recon_tomopy.array[67,50:90,50:90], recon_tomopy_abs.array[67,50:90,50:90]],
title=['Original image', 'Phase retrieval - thickness', 'Phase retrieval - scaled by mu', 'Phase retrieval - full_retrieval=False', 'Tomopy phase retrieval transmission', 'Tomopy phase retrieval absorption'], num_cols=3)

Environment

Experienced with CIL v24.1 and v23.1
