Electron Version

29.1.4

What operating system are you using?

Windows

Operating System Version

Edition: Windows 10 Home | Version: 22H2 | OS build: 19045.4170 | Experience: Windows Feature Experience Pack 1000.19054.1000.0

What arch are you using?

x64

Last Known Working Electron version

No response

Expected Behavior

Using a popup (alert or confirm) then trying to focus an input element shouldn't cause issues.

Actual Behavior

When the application is launched, there are no problems interacting with an input element.

After clicking on a popup from confirm or alert, trying to focus the window that just caused the popup (namely an input element) will no longer work.

Focusing on another window and refocusing the window repairs the issue.

Additional Information

I've noticed this issue for a while, but didn't catch onto the issue being caused by popups. I thought it was random and was caused by some strange interaction with focus that I was causing on my end. Having diagnosed the problem's cause, creating a Fiddle that could replicate it took seconds.

I mention this because it means the issue has existed for many major versions of Electron. How far back is unknown to me. But it goes at least as far back as version 21. I tried version 12.2.3 for fun with Fiddle and the problem persists.

I believe this is caused by the popup taking focus, but the window doesn't recognise that it gets focus back when the popup is closed. I also think this issue might be on Chromium's end. But I'm unsure since neither Chrome or Edge (the only other Chromium apps I have available to me) use the same kind of popup for alert and confirm or display this issue.

here is the main code..
function showAlert() {
alert("This is a test alert.");
window.focus();
}
function showPopupAndFocusInput() {
alert("This is a test alert.");
document.getElementById("myInput").focus();
window.focus();
}

I can confirm this on Ubuntu, however, I cannot confirm the claim that this has always been this way. The Fiddle works perfectly fine for me with v28.2.7 and breaks starting with v29.0.0-alpha.1. v27.3.6 and v26.6.10 also work for me.

I would not be surprised if Windows changed something that broke it for Electron.

@Maniiisha-sachdeva are you implying that calling window.focus(); after a popup will repair this focus issue?

I'll have to try this on Monday.

[LqdBcnAtWork]

I tried calling window.focus and .focus on an input element, and neither fixed the focus issue.

Also tried these versions:
(just the alert/confirm bug, not the focus function)

version       worked
28.2.7        ❌
27.3.6        ❌
26.6.10       ❌
21.0.0-beta.3 ❌ //the version of 21 that I noticed the issue with previously.
24.1.0        ❌ //version I had bumped the project to from 21.

Seeing that v28, v27 and v26 failed for me but not @Prinzhorn, I believe this is primarily a Windows issue. I can't test other versions of Windows unfortunatly. But I find it quite bizarre that it stops working on Ubuntu with v29.

Either way it's reassuring that it's not just me and my code. I'll have to implement a workaround for now.

edit: changed emoji for clarity.
