vscode/src/vs/workbench/api/browser/mainThreadCustomEditors.ts

Line 177 in 33df589

vscode/src/vs/workbench/api/browser/mainThreadCustomEditors.ts

Line 180 in 33df589

vscode/src/vs/workbench/api/browser/mainThreadCustomEditors.ts

Line 193 in 33df589

webviewInput.onMove(async (newResource: URI) => {
