Adding Sequences Package breaks 2021.2.0a20

When adding Sequences 1.0.0-pre.5, the 2021.2 alpha20 breaks with
Library\PackageCache\com.unity.sequences@1.0.0-pre.5\Editor\Startup\SetupMasterSequenceDragAndDrop.cs(32,35): error CS0426: The type name 'HierarchyDropMode' does not exist in the type 'InternalEditorUtility'

Considering one of the patch notes for a19 was Package: Added com.unity.sequences 1.0.0-pre.5 package., I’d assume this is a regression.

I was able to repro this. I will check how this could have happened since we have automated testing to ensure any released and pre-released package is tested. I will follow-up with the teams.

Hi @Soaryn !

This is a known issue, the Drag and drop API recently changed in 21.2.
It is already fixed in Sequences 1.0.0-pre.6.

Thanks for reporting, this is always appreciated.
