DataGrid rerenders even when it's not visible

Description (last modified by bill)

A (Data)Grid in a TabContainer continues to fetch data even when it's not (in) the selected tab; that doesn't sound right.

Patch attached; depends on #11988 and #11989.

Revisiting this, I'm not sure it's that wasteful to pre-fetch, since it makes tab switches instantaneous/quicker. Perhaps it's better to just make DataGrid?/_Grid more flexible w.r.t loading when hidden?

That's always the tradeoff between initial page-load speed vs. speed of switching tabs. This issue isn't specific to Grid though, same thing with ContentPane. ContentPane by default loads on show, although it has a prefetch=true flag.

The grid has the autoRender option which will keep it from rendering on startup and will wait to render until it is displayed.
