Suggest dropdown does not open when inputRef is set to ref hook

[tdehollain]

Environment

• Package version(s): Core@3.27.0, Suggest@3.13.0 core@3.28.0, select 3.13.1
• Browser and OS versions: Google Chrome 81.0.4044.129, MacOS 10.14.6

Repro code sandbox

Steps to reproduce

1. Click on the Suggest --> App crashes with error core_1.Utils.getRef is not a function
2. Change @blueprintjs/core version from 3.27.0 to 3.26.1 --> works

Your code sandbox works for me if I also upgrade the other packages, datetime and icons:

Can you check if you have multiple versions of core getting installed?

[tdehollain]

Indeed. I came to this while trying to reproduce a separate issue: when adding an inputRef prop to the Suggest component, the popover no longer shows when clicking on the input.
Should I edit the original post or create a new issue?

Maybe code sandbox is doing something weird where it doesn't respect dependency version ranges? select 3.13.0 explicitly depends on core 3.27.0, where Utils.getRef was introduced:

blueprint/packages/select/package.json

Line 38 in d08244b

"@blueprintjs/core": "^3.27.0",

any chance you could share a more realistic repro of the issue outside of the sandbox?

I'll look into this right now; I just made some changes to that code so I'll make sure it works before I release today.

Adding an inputRef to Suggest works fine for me on the latest develop branch. keep an eye out for a release today

[tdehollain]

Thanks. Seems like the bug is still present though, both on my local env and on codesandbox (updated the packages to yesterday's release).
I noticed that on Firefox the popover doesn't show at all but on Chrome it appears and disappears within like 0.1s.

Ok, I can repro the new problem in code sandbox with the latest packages: https://codesandbox.io/s/blueprint-sandbox-9w34k

The bug occurs with React.useRef, not with a callback ref. Latest docs site works fine.

I'm not sure what's happening here, but I can definitely repro the issue with the new feature added in select 3.13.0. Callback refs still work, so it's not a regression. Maybe @tanmoyopenroot (who submitted #4093) can take a look?

Hope you don't mind I updated this issue title and description @tdehollain

I am looking into it.
