Middle/Ctrl+click opens tabs in a wrong container

[WhiteSp1rit]

Problem:

Middle/Ctrl+click opens links in a wrong container, not the one configured in Containerise rules.
Then this tab closes, and a new tab in the correct container opens.

This possibly breaks the whole point of containers,
since the site gets access to information from the container not assigned to it.

To reproduce:

• set Reddit and Youtube to open in separate containers
• open a Reddit tab that has a link to Youtube in it, tab opens in a Reddit container
• Ctrl or middle-click a link to Youtube
• Youtube tab opens in a Reddit container
• Youtube tab closes
• New Youtube tab opens in a Youtube container

Expectation:
clicking a link navigating to a different domain should open it in a container assigned to it through Containerise rules

To my knowledge this happened in all versions of Containerise and FF on Windows since I installed it about a year ago
