Tab and app focus issues with nightly 1.77.3 1784

[Clumpton]

When switching tabs in the app (with mouse) the tab that has the focus needs a mouse click in the window to actually get the focus.
This has changed since the 2019 release.
Additionally, when MRng is behind another window, clicking in the visible area does not always bring it to the foreground.

Expected Behavior

Clicking on a connection tab should select the connection and give it the focus.
Clicking somewhere in the app when behind other windows should bring it to the front.

Current Behavior

On Putty-based connections the connection tab is shown but does not have the focus, a mouse click is required.
Clicking somewhere in the app when behind other windows randomly fails

Possible Solution

No idea

Steps to Reproduce (for bugs)

1. Open two SSH2 connections
2. Click on the tab of the 'inactive' connection to give it the focus
3. Note that the window is shown, but that the cursor is an empty rectangle
4. Start typing a command, realize that nothing is happening
5. Swear, click in the window and start typing again

Context

Most annoying when swapping between sessions
