[Question] Additional window opens behind main window, without focus

该报告没有提供可复现的代码示例、具名源文件或测试。首先缩减围绕 Window 创建、finalize=True、update() 和 read() 的表格编辑器场景，然后追踪 macOS 上 tkinter 的窗口和焦点行为。要视为完成，必须确认原因并得到可复现的修复。

Have used another Python GUI Framework? (tkinter, Qt, etc) (yes/no is fine) no, I'm a back-end guy

Anything else you think would be helpful?
This is the same application that was exhibiting the Alpha Channel issues (thank you for the help on that!)

Troubleshooting

These items may solve your problem. Please check those you've done by changing - [ ] to - [X]

• [ x] Searched main docs for your problem www.PySimpleGUI.org
• [ x] Looked for Demo Programs that are similar to your goal. It is recommend you use the Demo Browser! Demos.PySimpleGUI.org
• If not tkinter - looked for Demo Programs for specific port
• For non tkinter - Looked at readme for your specific port if not PySimpleGUI (Qt, WX, Remi)
• [ x] Run your program outside of your debugger (from a command line)
• [ x] Searched through Issues (open and closed) to see if already reported Issues.PySimpleGUI.org
• [ x] Have upgraded to the latest release of PySimpleGUI on PyPI (lastest official version)
• [ x] Tried using the PySimpleGUI.py file on GitHub. Your problem may have already been fixed but not released

Detailed Description

Ok, I wish I could give you code to reproduce but this is in a set of dataframe / table editor classes that's 1,200 lines long and I haven't found a small set of code to reproduce the issue. I've been chasing this on my own for several weeks, and haven't posted here since I don't have a succinct code fragment to share. Finally decided to see if you could suggest an area to focus on my debugging.

Here's the situation:

1. Create a table layout made out of Text for headers, Checkbox elements at the start of each row, and Input elements for each cell of the table. The table also includes navigation and action Button elements
2. The Window is finalized (finalize=True in call to the Window constructor) before any updates are made Window elements
3. Values are populated into the table with a sequence of update() calls
4. I'm not calling any of the focus setting methods
5. The event loop uses a normal blocking call to read()

Here's the problem:

• The main Window draws and behaves fine
• However, when an event (usually a button press) causes a second window to be created, that window is created without focus and behind the main window.
• I see the new window get drawn, and then a flash as the original window is redrawn on top.
• Focus remains on the main table window, not the newly created window, even though the next call to read() is on the newly created window.
• Meaning, this is not multi-threaded. The event loop for the main window is blocked waiting for the actions on the newly created window to complete.

I've messed with trying to set focus on the new window when it's created. The best I get when chasing down that path is that the new window draws on top as expected, but as soon as I move the cursor (mouse movement) the initial main window pops back to the top.

Now, if I toggle active windows (Cmd-` on a Mac), the new window stays on top and behaves as expected.

Thoughts on paths I can chase down to find what I'm doing wrong? Or thoughts on places in the the PySimpleGUI source that I could breakpoint to chase down what's up?
