macOS: ⌘F does not launch a search and but an explicit call to browser.host().find(...) does not do anything (it works on Windows/Linux)

[Q1zin]

Summary

On Windows and Linux, the page search is launched both through a shortcut (Ctrl+F) and through an explicit call to browser.host().find(...). On macOS, neither ⌘F nor a direct call to find(...) they have no effect: there is no search and no result events are received.

Platform Information

• Affected Platform: macOS (aarch64-apple-darwin and x86_64-apple-darwin)
• Working Platforms: Windows (x86_64-pc-windows-msvc), Linux (x86_64-unknown-linux-gnu)
• CEF Version: I'm testing on 140.3.1
• Configuration: Your cefsimple

Problem Description

When calling BrowserHost::find() on macOS, the find operation is silently ignored:

• browser.host().find(Some(&query), 1, 0, 1) executes without errors
• ImplClient::find_handler() is never called by CEF
• ImplFindHandler::on_find_result() is never invoked
• No find results are reported

Did you register the find_handler in DemoClient?
