Reproduction steps:
1. Create and open a new project
2. Create a new GameObject in the Hierarchy
3. Add multiple Components to the GO until you need to scroll the Inspector
4. Press and hold the left mouse button on the three dots (hamburger menu) on one of the Components
5. Move it over the closest opened option
6. Release LMB
7. Observe the behaviour

Expected result: Nothing happens after LMB is released (only then I'd expect the Context Menu to appear)
Actual result: The hovered-over option is selected upon LMB release and the Context Menu closes

Reproducible in: 2023.1.0a1, 6000.0.58f1, 6000.2.4f1, 6000.3.0b2

Reproduced on: Windows 11 Pro (24H2)
Not reproduced on: No other environment tested

Notes:
- On the 5th step, if too little space is given for the Context Menu, the menu will open already under the cursor, making the issue more apparent and making you instantly hover over some option
- This also affects other Context Menus in the Editor, except for the ones in the Scene view or the Toolbar
