 - SVG images with `.img-fluid` are sometimes disproportionately sized. To fix this, add `width: 100%;` or `.w-100` where necessary. This fix improperly sizes other image formats, so this isn't applied automatically.
 - There is a slight delay before the ie11CustomProperties polyfill works its magic. Consider adding `body{font-family:"Segoe UI", Arial, sans-serif;}` to your IE11-only stylesheet so there isn't a delay in the text displaying.

+- From Bootstrap 5.2 onwards, CSS custom properties are used extensively which can cause issues with the ie11CustomProperties polyfill.
