quickLookup - drop down with records overflows screens that have the enahanced lightning UI enabled

[bacasystems-IT]

Steps to reproduce

https://github.com/alexed1/LightningFlowComponents/tree/master/flow_screen_components/quickLookup

Steps to reproduce the behavior:

1. Open an org that has the new enhanced lightning enabled in it.
2. Create at least like 150+ records of any object you want (in this case, use opportunity)
3. Create a screen flow, then add a screen to it
4. Add the Quick Lookup component to the screen
5. Just keep it simple and use the Opportunity as the object, display the name, and don't add filters
6. Save and activate the screen flow
7. go on any lightning page and edit it to add the screen flow to the page, save and activate
8. observe the drop-down overflows the flow and shows 100 records
9. If you turn off enhanced lightning, it will function normally.

Expected behaviour

The screen should only display a few drop-down options and then progressively filter

Actual behaviour

it shows 100 records

I believe the issue is that the slds-lookup is deprecated.

They deprecated slds-lookup and replaced with slds-combobox and slds-combobox-group (2dbe619)

Attached is the sarrif from the SLDS validator
