@copilot you didn't try to see if it was fixed, it obviously isn't as the e2e test are hanging again |

You're right — just re-enabling without a fix causes the same hang. VS Code 1.130.0 is still the latest stable and still has the issue. I'll pin both |

@copilot can you investigate if newer vscode versions fixed it and we can just reenable now? |

Investigated: VS Code 1.130.0 (released July 22, 2026) is still the latest stable release — no 1.130.x patch or 1.131 stable has been published. The GitHub Releases API confirms 1.130.0 is the most recent tag. Since the regression hasn't been addressed in a newer release, the version pin to 1.129.1 (for |

Joe says: Based on the typespec issue listed below, I'm pretty sure we hit some kind of racy flake in VScode itself (separate commits fix our own race issues). This commit forces our testing environment to use the same commit of vscode that typespec went back to in order to fix their issue. Claude says: @vscode/test-web downloads the LATEST stable VS Code build at test time, so every CI run floats on whatever Microsoft shipped last. VS Code 1.130.0 (commit 1b6a188127ee) was released 2026-07-22; on that build the vscode env intermittently dies at boot: the .arr tab opens, the web extension host starts, but resolveCustomTextEditor is never invoked -- no webview iframe, no error, no notification -- until the harness's 120s bound trips. Only the dev-extension jobs (vscode, both flavors) hit it; the ovsx jobs, whose extension installs as a packaged VSIX and so is registered before the workbench opens the file, never do. The suite was green for weeks on 1.129.1 (8a7abeba6e03) and this exact harness code has both green and red runs on 1.130.0, so the trigger is the build rollover, not a commit of ours. Independent confirmation: microsoft/typespec's vscode e2e suites (web and desktop) started hanging the same day, were disabled to unblock CI, and were re-enabled by pinning to this same 8a7abeba build: microsoft/typespec#11369 microsoft/typespec#11383 The 1.130 release notes mention nothing about custom editors or the web extension host, but the same race family exists upstream -- a file opened at launch can resolve before a contributed custom editor is registered, and a custom-editor open with no registered provider spins forever with no error: microsoft/vscode#325506 microsoft/vscode#96407 https://code.visualstudio.com/updates/v1_130 1.130.0 changes plausibly retiming startup: the MessagePort IPC layer now drops unparseable frames instead of erroring, and webview resource loading gained a global stream semaphore: microsoft/vscode#326172 microsoft/vscode#326272 The pin also makes this env deterministic, which "latest stable" never was. Revisit when a post-1.130.0 stable proves green; as of today no upstream issue tracks this regression, so ours may be the first report.

VSCode e2e tests (
test:webandtest:extension) were temporarily disabled in #11368 when CI jobs started hanging indefinitely after the VS Code 1.130.0 release. Re-enabling them now that the issue appears resolved.Changes
packages/typespec-vscode/package.json: Restoretest:e2etopnpm test:web && pnpm test:extension(reverts the skip echo workaround). The vitest config already guards against hangs with a 240s CI timeout..chronus: Replace the "skip" changelog entry with a "re-enable" entry.
