Martin Brennan db80a8ce79 FIX: Preload fonts before rerendering wizard style canvas (#22361) ... ]When changing fonts in the `/wizard/steps/styling` step of the wizard, users would not see the font loaded straight away, having to switch to another one then back to the original to see the result. This is because we are using canvas to render the style preview and this fails with a Chrome-based intervention when font loading is taking too long: > [Intervention] Slow network is detected. See https://www.chromestatus.com/feature/5636954674692096 for more details. Fallback font will be used while loading: https://sea2.discourse-cdn.com/business7/fonts/Roboto-Bold.ttf?v=0.0.9 We can get around this by manually loading the fonts selected using the FontFace JS API when the user selects them and before rerendering the canvas. This just requires preloading more information about the fonts if the user is admin so the wizard can query this data.		2023-07-03 11:30:26 +10:00
