This Idea follows on from this Question: https://community.esri.com/t5/arcgis-experience-builder-questions/is-it-possible-to-set-the-minimum-width-of-columns/td-p/1653553
I'm building an Experience using the Grid layout which consists of three columns. I'm using the Grid layout because it automatically switches to a mobile-friendly view at small screen widths, which is what I need. However, there doesn't seem to be any way of specifying a minimum width on each of the columns. Here's what it looks like at 1024x768:

This is fine, but I wouldn't want the two left most columns to get any narrower, but if you make the window narrower, the columns shrink to the point that they're basically unusable. Here it is at 600px wide:

What I'd like to do is set minimum widths on the two left most columns in pixels so that I have control over how narrow they get.
