Performance Issue when overview of many templates as a grid is displayed #64521

Description

If I use many different templates (for example 30 templates) with a block theme such as Twenty Twenty-Four, it takes a very long time until the overview is displayed under Appearance > Editor > Templates as grid. I have just deactivated all plugins (23 plugins, including many lightweight plugins). As expected, the template overview is displayed a little faster as a grid. But that doesn't seem to be decisive. Performance is ok in list or table view.

This issue might be similar to https://github.com/WordPress/gutenberg/issues/64219 which flags a performance issue with the patterns page. There's a possible fix up for that in https://github.com/WordPress/gutenberg/pull/64606.

Perhaps the templates page may need a similar fix while work on other improvements such as https://github.com/WordPress/gutenberg/pull/64504 continue?
