Problem

If keyboard-navigation is also used, new context menu items are added which use the precondition from the old shortcuts. This means the precondition expects that there is not an in-progress gesture in order to enable the option. Because a gesture is always in progress when right-clicking a block, the option always ends up disabled.

Request

Replace the gesture check with an in-progress drag check, similar to https://github.com/google/blockly/pull/9107
