Does it still scroll if I have the chat open in a call on my second screen and work in my IDE on the other screen?

Filling the truth table for 5 arguments we're using:

🛑 - no scroll at all
❎ - half scroll, user haven't read recent messages
🔽 - to the bottom, user is reading everything
bg - background, tab not visible
fg - foreground, tab visible (on a second screen)
ATB - chat is already at the bottom
⚠️ - was changed with that PR
🚀 - nice to have

Remark: Before has only these rules applied, so behavior might differ a bit:

• force: true - 🔽 upload file only
• isSticky - ATB + messages loaded (not new chat) - 🔽 new messages, new reactions
• isVisible && (hasFocus || isInCall) - 🔽 click to bottom, posting , otherwise ❎ half scroll

Remark: !isVisible && hasFocus is impossible case, omitted from table

if isWindowVisible is falsy, it drops all other cases for you, and when it comes to second if block, you don't have to check for visible/focus/sticky
force should be truthy if you posting a message/file, or at the chat opening, to scroll to the focused / first unread

Looking at the cycle, isInCall and hasFocus can be omitted, and 'force' treated separately before other logic:

if (force) {
    🔽 
} else if (!sticky) {
    🛑 
} else if (!visible) {
    ❎ 
} else {
    🔽
}
