[BUG] Pressing "Esc" doesn't close chat if window has particular width

Describe the bug Pressing "Esc" doesn't close chat if window has particular width

To Reproduce Steps to reproduce the behavior:

I have desktop. With Google Chromium on Desktop
I'm nearly sure that this bug can be reproduced on any desktop OS (Windows, Linux, macOS). But my OS is Linux
Computer should not be configured as HiDPI system, i. e. screen scaling should not be enabled. Also, zoom settings for https://web.telegram.org/k/ should be set to 100%. All these ensures that hardware pixels correspond to CSS pixels
Open browser window, resize it so that height becomes 500 pixels and width becomes 1000 pixels
Go to https://web.telegram.org/k/ . (I assume here that you are already authorized. Also I assume that you already have some chats in your account.)
Choose some chat from list of chats, located in the left. Click on chosen chat using mouse
This will cause this chat to open. Also URL will change from https://web.telegram.org/k/ to something else, for example, to https://web.telegram.org/k/#@foo or to https://web.telegram.org/k/#123456789
Note that the window is big enough, so both list of chats and chat itself will be visible
Now press "Esc"
The chat will remain opened (!). Both chat and list of chats will remain visible. But URL will change back to https://web.telegram.org/k/

Expected behavior After pressing "Esc" the chat should close and URL should change back to https://web.telegram.org/k/

Current behavior is wrong for two reasons:

Pressing "Esc" doesn't close the chat
Pressing "Esc" brings us to strange situation: chat is opened, but ID or nickname is not shown in URL. I think this should never happen

Desktop:

OS: Debian Linux Stretch, my screen resolution is 1920 * 1080. I use X server. My system is not configured as HiDPI system
Browser: Chromium 121.0.6167.160
