Parser can not handle generic typed classes with interfaces

[d1820]

tsco.json

When trying to organize a class that is generic

export class MYComponent<T extends keyof typeof ComponentProviderMap = 'TextBox'>
  implements ICustomElementViewModel { }

it ends up cutting out part of the class line

export class MYComponent<T extends keyof typeof ComponentProviderMap = 'TextBox'>
  im

Seems like the generic <> is not playing nice with the parser

looks like it may also be related to using decorators on the class

@customElement('my-component')
@inject(ILoggingService)
export class MYComponent<T extends keyof typeof ComponentProviderMap = 'TextBox'> implements ICustomElementViewModel {}

export class MYComponent<T extends keyof typeof ComponentProviderMap = 'TextBox'>
  im
