On android I take a screenshot and use the lens tool in my photos app.
The screenshot tool has a lens feature too but that one only offers opening the link while photos will also let me copy the URL without sending it to my browser.
In this case it is: https://watchdominion.org/
Lens is also good for OCR with built in copy to clipboard and translation features. As you can screenshot most apps or take a photo of a sign, letter, gift card, etc. it can be a handy little tool.
I feel like this has been the case for a while now. Luckily they offer other search tools so its a gotcha that you only have to hit once.
In edit mode they capture the crtl-f keystrokes and offer their own search and replace tool. An argument could be made that they should offer a custom search tool for read mode if they are going to break the browsers built in tooling.
