Verified on the latest Nightly 101.0a1 (2022-04-15) using the following flow:

• long tap on a linked text/linked image > tap on every option from the context menu;
• long tap on text > Copy;
• Paste the copied text in a search bar.

@mcarare These are the only events that were observed by us:

Device used: Google Pixel 6 (Android 12).

@delia-pop Thank you for testing!
This should be fixed in the next nightly or current main branch.
