[24.0] Prevent dragover for item from same history in history panel

[ahmedhamidawan]

We would allow users to dragover items from the same history over its panel and render the dropzone, this prevents that entirely. Fixes #17743

Before:

dropping_same_history_before.mp4

Now:

dropping_same_history_after.mp4

works well, would you mind incorporating similar fix for the clickable area as in #17621?

Ah good pick, the content item draggable area needs to be larger as well

@martenson I made the whole ContentItem draggable, I hope this works better?
