Updating rc9.1 -> rc9.2 ignores unsaved sketch

[aliphys]

Describe the problem

The IDE automatically looks for updates and informs the user. Prior to updating, the user is asked to close and update the software. When you have an unsaved sketch and want to update the IDE, the IDE asks you to save the current sketch but goes ahead with the installer anyway.

The unsaved sketch is then forced closed, which may lead to loss of work.

To reproduce

1. Open Arduino IDE 2.0.0rc9.1
2. Make a sketch, but do not save it
3. Download rc9.2 when asked to
4. Once rc9.2 has been downloaded, click on Close & Install
5. Ignore the window asking you to save
6. Install IDE rc9.2
7. The previous version of the IDE (rc9.1) is forcefully shut down without any warning

Expected behavior

The installation procedure does not proceed until the unsaved sketch is taken care of.

Arduino IDE version

IDE 2.0.0-rc9.1

Operating system

Windows

Operating system version

Additional context

Issue checklist

• I searched for previous reports in the issue tracker
• I verified the problem still occurs when using the latest nightly build
• My report contains all necessary details

Thanks @aliphys. I also noticed this behavior, and wondered whether it might be the cause of the reports like #1163. I was not able to reproduce #1163 by doing an update with an open save confirmation dialog though, so probably it is not the case.

But as you point out, this is problematic in other ways even if it does not interfere with the update.
