1545027 - Proxmox NoVNC keyboard capturing failures

Status: RESOLVED INCOMPLETE

(Core :: DOM: UI Events & Focus Handling, defect, P2)

Description

[x.m3atr.x]

User Agent: Mozilla/5.0 (Windows NT 6.3; WOW64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/71.0.3578.98 Safari/537.36 Vivaldi/2.2.1388.37

Steps to reproduce:

1. Log into a Proxmox Server at https://x.x.x.x:8006
2. Look at the NoVNC console for a VM running windows 2012 server

Issue #1: (after step 2)
3a) Go into a browser inside of the VM
4a) push ctrl + W on keyboard
5a) Proxmox tab on Firefox that is at https://x.x.x.x:8006 will close instead of tab inside of VM

issue #2: (after step 2)
3b) Inside of VM, change the focus to any inputbox
4b) Starting typing
5b) maybe 15% of the time, 1-5 characters will be sent to VM and displayed and then no other typing can be done unless I click on the inputbox again at where I left off (This repeats once it starts and I just switch to chrome)

Actual results:

Issue #1) Firefox tab closed on the PC being used

Issue #2) I can no longer type after 1-5 characters

Expected results:

Issue #1) Browser Tab on VM should be closed

Issue #2) All characters should be sent to VM without interruption

Hi,
we do not have the proper environment to reproduce that bug but it seems related to a keyboard problem so i'm setting a component but feel free to change it if you consider it is not the right one. Best regards. David

This is by design. We don't allow web apps to override some critical shortcut keys (mainly related to tab navigation). You can change this behavior per domain. See "Page Info" -> "Permissions" -> "Override Keyboard Shortcuts".

3b) Inside of VM, change the focus to any inputbox

Which version of Firefox are you using? And which keyboard layout are you using? Is this new regression of Firefox? But I've not gotten such bug reports with any other web apps... So, it seems that focus is changed in the web apps accidentally. Could you report it to their bugzilla and let us know the bug ID?

Dear reporter,
Thank you for reporting the issues. Please feel free to reopen it, when you get a chance to get back here for comment 3 and the issue is still valid on the latest Firefox. Thank you again.
