Steps to Reproduce

Run fiddle as a standalone page.

https://zkfiddle.org/sample/384b0g4/2-Another-new-ZK-fiddle

Open developer tools, set userAgent to Ipad to mimic a touch and mouse device such as laptop with touch screen.

Press the button "do a thing" to trigger a zkau request

Press the button "show groupbox" to show the grid

Current Result

hflex="min" is calculated incorectly

Expected Result

hflex="min" is calculated correctly

Debug Information

onResponse listener triggers with the above conditions.

During onResponse, grid#doResizeScroll is invoked, calculating the hflex="min" sizes for grid columns.

If this happens onResponse while the grid is not visible, the size are calculated based on the non-rendered grid content.

When the grid is made visible, it doesn't re-calculate min flex.

Workaround

Prevent grid to trigger doResizeScroll if not visible
