Though this page does have some links highlighted in blue, when you
mouse over something else, for me it does not highlight the copied part
and appears to not be copying at all. By accident, I saw the DeepL icon
pop up and thought it must actually be copying it. So I tried to copy
and paste and sure as hell it does copy without highlighting and you can search on what you want in pages like this.

I had not noticed this behavior before, and wonder how they get the
browser to think you can't do that by hiding the highlighting? I
checked other pages, and now realize the copied text seems to be of a
color that can be different, and must be defined in the page somehow.
So to do this they define highlighted text as not having a color, or transparent? I noticed it on this page below if you haven't seen this
before either.

Doesn't seem to do anything "bad" to me, but normally that sort of hack
is done with javascript intercepting click or copy events, try with js disabled.

Did not change with JS disabled, but switching to reader view allowed
the copied text to be highlighted. I've seen before where copying
appeared not to work, just never noticed it before in this context.

It "highlights" for me in very pale grey, only just distinguishable from
the background. The highlighting is a paler blue than usual in Reader mode.

I think the subtly different blues are the difference between
<a> tags using --article-body-list-link-color
while <a:hover> uses --article-body-list-link-hover-color

The pale grey background will be something like a <p::selection>
but I can't find it

Scripts on Web pages can intercept left-clicks and right-clicks, but
Firefox seems unique in not allowing interception of shift-right-click. So this should still work to bring up the context menu even if the page tries
to block it.

If I understand you correctly, this can be done in CSS by using ::selection pseudo-element. Many attributes can be set to a user selected text (background, foreground etc.)

You can try it here (set the color on the left side, press "Run" button and select the text on the right side):

Yep, you nailed what I'm seeing. If you remove both the color value and
the background value, it still will copy what you select, but nothing is highlighted.

Kind of funny on that page, they misspelled selection as selction.

Thanks! Now I know it's CSS and not javascript.
I'll go and see if this is in the page I referenced.
