[Bug]: hop-web GUI crashes when trying to copy to clipboard

[gmitter-ef]

Apache Hop version?

apache/hop-web:2.11.0

Java version?

openjdk 17.0.2 2022-01-18 OpenJDK Runtime Environment (build 17.0.2+8-86) OpenJDK 64-Bit Server VM (build 17.0.2+8-86, mixed mode, sharing)

Operating system

What happened?

Using the Web GUI container under RHEL 9.4 host, any attempt to try to copy a dummy step leads to an error.
Neither "CTRL+C" nor "Copy to clipboard" works.

How to reproduce:

• startup a container with the 2.11.0 hop-web image
• open the default project
• create a new pipeline
• add the dummy transform
• select the dummy transform and press CTRL+C or use the "Copy to clipboard"

Error:
org.eclipse.swt.SWTError: Cannot set data in clipboard
...

See the screenshots.

Can you make sure copy permission is enabled on the browser (guides on how to check)?
A lot of browsers block copy/paste from websites with invalid certificates.
And which browser are you using? I tested with the latest development build and Chrome and copy seems to be working as expected.
