Expected behavior:
Should compile, like with Stencil 2.13.0

Steps to reproduce:
Create a new Stencil starter 'app'. This has Stencil 2.13.0 as a dependency. Update to Stencil 2.14.0 or higher. Compile.

Presumably the same problem as with Ionicions / aria attributes: ionic-team/ionicons#1011

In a different context but the same issue. Isn't it possible to change the TS version?
