Bug Description

We use FullCalendar in Angular project. And today recently build start to fail constantly. As I see, there is a dependency in @fullcalendar/core from “preact”: “^10.0.5” and it is not strict. Several hours ago this preact package was updated to the version 10.13.0.

  "devDependencies": {
    "@angular-devkit/build-angular": "0.1102.12",
    "@angular/cli": "11.2.12",

Error:

✔ Browser application bundle generation complete.
Error: node_modules/preact/src/jsx.d.ts:2138:24 - error TS2304: Cannot find name 'SVGMPathElement'.
2138  	mpath: SVGAttributes<SVGMPathElement>;

As a quick fix: add preact packages 10.0.5 as dev dependency. But this is temporary solution!
