enterPredicate called every cdkDropList

[ryanOhh]

enterPridicate is called on every cdkDropList on dragMove.

Reproduction

Use StackBlitz to reproduce your issue: https://stackblitz.com/fork/components-issue

working

Steps to reproduce:

Expected Behavior

What behavior were you expecting to see?

• I was expecting enterPredicate to only work on the drop target cdkDropList when dragging and dropping.

Actual Behavior

What behavior did you actually see?

• Only the drop target cdkDropList does not work and enterPredicate is called on all cdkDropLists.
• cdk 7.1.1 will work as intended, but 8.2.0 will not work as intended.

Environment

• Angular: 8.2,0
• CDK/Material: 8.2.0
• Browser(s): chrome

@crisbeto Hello! Could you tell me, when the issue's PR will be merged and new version of cdk will be published to npm? We want to release a new version of our app in a few days, and just don't know, should we wait for this bug fix? Thx a lot :)

This isn't super high on our priority list so it probably won't make it into release within the next few days.
