This updates the widgets screen to load the editor styles in the same way as the post editor. This combined with the package updates in [51198] and [51199] ensures that the blocks added to sidebars more accurately reflect what will be displayed on the front end of the site. Props isabel_brison, noisysocks, andraganescu, audrasjb, jorbin, caseymilne, desrosj. Fixes #53344. See #53388.
