Middle click on link opens new browser window inside Electron

[imtbl]

Environment

Joplin version: 1.0.201
Platform: Linux
OS specifics: Arch Linux (installed via https://aur.archlinux.org/packages/joplin/)

Steps to reproduce

1. Add link to note (e.g., [https://duckduckgo.com](https://duckduckgo.com))
2. Middle click link in note viewer
3. New browser window opens inside the Electron application

Describe what you expected to happen

According to here, this should probably not be possible:

joplin/ElectronClient/main-html.js

Lines 87 to 88 in 0f7deee

	// Disable middle-click (which would open a new browser window, but we don't want this)
	document.addEventListener('auxclick', event => event.preventDefault());

Imo, if possible, this should rather open a new tab/window inside the configured default browser (essentially treating it as a left click should suffice for this, I guess).
