Missing import suggestions (in *.tsx) for some components from node_modules (npm)

[mrGibi]

• VSCode Version: 1.31.1 & 1.32.0-insider; extensions disabled
• TypeScript version: 3.3.1 & 3.4.0-dev.20190307
• OS Version: macOs 10.14.3

VSCode doesnt find (?) and suggest importing SOME components installed from npm.
Examples when there are no import suggestions:

• npm install @material-ui/core (type defs included)

^ no suggestions. If I `import {}` from this package suggestions are shown:

Another one:

• npm install react-bootstrap (type defs included)

^ again, no suggestions, but if I `import {}`:

Exactly same with (for example) @fortawesome/react-fontawesome (FontAwesomeIcon component) (type defs included).

One example where import suggestion DOES show up:

• npm install reactstrap (type defs not included)
• npm install @types/reactstrap

^ suggestions are working as expected

Does this issue occur when all extensions are disabled?: Yes

This sounds like the limitation described in #29039 (comment)

Package auto imports only start showing once there an existing reference to that package somewhere in the project
