fix: do not open DevTools if it is already open#3443
Merged
Conversation
Ports upstream Puppeteer PR #14922. Extracts GetDevToolsTargetPageAsync from CreateDevToolsPageAsync in CdpBrowser, and updates OpenDevToolsAsync in CdpPage to check for an existing DevTools target before opening a new one — preventing focus stealing when DevTools is already open.

Summary
Ports upstream Puppeteer PR #14922.
GetDevToolsTargetPageAsync(string devtoolsTargetId)as a new method inCdpBrowser, refactoringCreateDevToolsPageAsyncto delegate to itCdpPage.OpenDevToolsAsync()to first check if a DevTools target already exists viaHasDevToolsTargetAsync— if so, returns the existing DevTools page without re-opening (which would steal focus)IPage.OpenDevToolsAsyncXML doc comment to reflect the new "if not already open" behaviorProblem: Opening DevTools steals focus. If DevTools was already open and the page called
openDevTools()again (e.g., from a background tab), it would steal focus unnecessarily.Fix: Check for an existing DevTools target first. If one exists, return the existing DevTools page instead of triggering
Target.openDevToolsagain.Test plan
dotnet build lib/PuppeteerSharp/PuppeteerSharp.csproj— succeeded with 0 warnings/errorsOpenDevToolsAsync()twice returns the same DevTools page without re-focusing🤖 Generated with Claude Code
