Detailed Description of the Pull Request / Additional comments

Demo:

• Holding the SHIFT key while releasing the primary mouse button keeps the current measurement displayed instead of hiding it.
• Clipboard handling: all active measurements are copied to the clipboard when there are multiple measurements. Bounds tool also made to work this way.

Validation Steps Performed

• Tested existing functionality as described here
• Tested new functionality - multiple measurements / bounds by holding SHIFT key and releasing or hitting ESC. Some multiple measurements were made on multiple monitors.

Gave it a quick test. I think the Bounds measure behaves a bit weirdly.
When you press shift and take measurements and then you release shift and try to take more measurements, those don't stick but stay in the same mode 🤔 Not sure this makes sense as user interaction.

Other than clipboard handling, the Bounds tool hasn't been changed - only the measuring tools have, so the behavior you mention is an existing one. Having said that, I think it's actually quite logical - the heuristic is "Hold SHIFT to keep this box, otherwise forget it."
