Autocompleter in an Angular Library

Expected behavior I am trying to build a library for my shared components. I have added mdb-bootstrap to my library. For all components, this works great. However for autocompleter i get the following errors:

Error: projects/mdb-pro/src/lib/autocompleter/autocompleter.component.html(1,1): : Directive MdbAutoCompleterDirective, Property '_handleInput' is protected and only accessible within class 'MdbAutoCompleterDirective' and its subclasses.
projects/mdb-pro/src/lib/autocompleter/autocompleter.component.html(1,1): : Directive MdbAutoCompleterDirective, Property '_handleKeyDown' is protected and only accessible within class 'MdbAutoCompleterDirective' and its subclasses.
projects/mdb-pro/src/lib/autocompleter/autocompleter.component.html(1,1): : Directive MdbAutoCompleterDirective, Property '_handleFocusIn' is protected and only accessible within class 'MdbAutoCompleterDirective' and its subclasses.
projects/mdb-pro/src/lib/autocompleter/autocompleter.component.html(1,1): : Directive MdbAutoCompleterDirective, Property '_handleBlurIn' is protected and only accessible within class 'MdbAutoCompleterDirective' and its subclasses.
projects/mdb-pro/src/lib/autocompleter/autocompleter.component.html(1,1): : Directive MdbAutoCompleterDirective, Property '_handleMouseDown' is protected and only accessible within class 'MdbAutoCompleterDirective' and its subclasses.

I am not accessing any of these protected methods directly.

Actual behavior

This would hopefully work like all other MDB components.

Resources (screenshots, code snippets etc.)

I recreated this issue in git. The readme outlines everything.

But it shows autocompleter working when running in the main application, and failing when in a library.

Because this is a pro-element, i xxxxx'd out my token from the package.json file. ( In both the main one, and the Library file)
