Reduced test case

No need for a test case

Steps to reproduce

Just install video.js and run a TypeScript check with this tsconfig.json:

{
  "compilerOptions": {
    "target": "ESNext",
    "allowJs": false,
    "allowUnreachableCode": false,
    "allowUnusedLabels": false,
    "forceConsistentCasingInFileNames": true,
    "moduleResolution": "Node",
    "useDefineForClassFields": true,
    "strict": true,
    "exactOptionalPropertyTypes": true,
    "noUncheckedIndexedAccess": true,
    "newLine": "lf",
    "noFallthroughCasesInSwitch": true,
    "noUnusedLocals": true,
    "noUnusedParameters": true,
    "noImplicitOverride": true,
    "noImplicitReturns": true,
    "noEmitOnError": true,
    "noEmit": true,
    "verbatimModuleSyntax": true,
    "declaration": true,
    "declarationMap": true,
    "inlineSourceMap": true,
    "inlineSources": true,
    "baseUrl": ".",
    "module": "ESNext",
    "experimentalDecorators": true
  }
}

The only workaround is adding "skipLibCheck": true.

Perhaps related to #8141.

Happens on TypeScript 5.1.3 but most likely it happens also on older versions.
