Canceling Drag and Drop with ESC immediately hides dropzone bar (#24204)

[mreishus]

Description

fixes #24204

When canceling a drag and drop operation by pressing "ESC", the blue dropzone bar will now immediately disappear.

Previously, it would only disappear after the next "Mouse Up" event. If you pressed ESC, kept the mouse button held, moved the mouse outside the browser then released the button, the blue bar would be showing indefinitely.

How has this been tested?

Tested manually by running wp-env start and npm run dev.

Types of changes

• Bug fix: The isDraggingBlocks() selector is now also checked when deciding to render the is-drop-target class. Previously, only the dropTargetIndex was being checked.
