Please provide a short description of the issue:

With new Google Sheets:
The setActiveSheet method does not set the focus on the sheet (at the interface) when run from a trigger onOpen (Simple or Installable). If we run the onOpen from the code editor works correctly.

Please provide a small sample script that reliably reproduces the issue.
The sample should run as-is or with minimal setup, without external
dependencies.

function onOpen() {
  var ss = SpreadsheetApp.getActiveSpreadsheet();
  var sheet = ss.insertSheet();
  ss.setActiveSheet(sheet);
}

What steps will reproduce the problem?
1. Create a new spreadsheet.
2. Insert the code.
3. Close and open the spreadsheet.

What is the expected output? What do you see instead?

Expected output is the newly inserted sheet is active.
I see the first active and not the new sheet.

Please provide any additional information below.

This happens with the new version of Google Sheets, executing the same code with the old version of Google Sheets works as I expect, however, two sheets are inserted instead of one. For correct operation in the old version must be made via an Installable Trigger.
