Delay rendering preview for pasted URIs

[blowdart]

Is your feature request related to a problem? Please describe.

Often when you want to share a URI from the likes of Instagram, or paste from a URI you clicked through from a newsletter the URIs will contain share identifiers you would like to remove before your post is made, both for your privacy and for that of others who will click your link.

Unfortunately, as soon as you paste a URI into the app the client side preview kicks in, generating a thumbnail/card link with the share identifiers. While you can manually remove the preview, then go back and delete the share IDs from the URI, then press space to make the preview recreate itself this is not intuative, or easy to do, and the preview generation immediately indicates to the tracking site that you're sharing.

Describe the solution you'd like

Step 1

Delay generating the preview link until a "key" press happens, other than delete, or navigate keys. This would allow the user to delete the parts of the URI which are there for tracking purposes, and avoid having the preview render indicating it's been shared by the user.

Step 2

Adding automatic stripping of well-known share identifiers on URI paste or entry would go furtherin protecting privacy, as users do not often recognise the tracking parameters and remove them.

https://raw.githubusercontent.com/DandelionSprout/adfilt/master/LegitimateURLShortener.txt has a decent list.

Additional context

Until recently it did require a click to generate a preview card. I requested that behavior be retained as an option for this very reason, a while ago - see my comment on #2321.

It looks like #5323 is the same issue as this.

It's never required a click for me when pasting on iOS.

Automatic previews were added in April (#3566), I'm talking about before that.
