Optional resolver doesn't work as expected about dependency-injection

[Alexander-Taran]

can you provide a small repro?
reading the source revealed no misuse of false

Optional

dependency-injection/src/resolvers.js

Line 125 in 6205549

if (container.hasResolver(this._key, this._checkParent)) {

getResolver

dependency-injection/src/container.js

Line 338 in 6205549

return this._resolvers.has(key) || (checkParent && this.parent !== null && this.parent.hasResolver(key, checkParent));
