What actually happened?

ERROR in node_modules/pdf-lib/ts3.4/cjs/api/form/PDFDropdown.d.ts:400:38 - error TS2502: 'provider' is referenced directly or indirectly in its own type annotation.

What did you expect to happen?

Speculation is that the merge error is caused by the TS version being too high

How can we reproduce the issue?

"pdf-lib": "^1.17.1", "typescript": "3.4.3", "rxjs": "6.4.0", "@angular/core": "8.2.14",
