Steps to reproduce

1. Lunch Firefox and reach Wikipedia.
2. Select a hyperlink composed of at least two words (long press).

Expected result

• The context menu is opened and all the words in the hyperlink are underlined. None of the words in the hyperlink are highlighted and selected.

Actual result

• The context menu is opened, all the words in the hyperlink are underlined, but the word that was long pressed is highlighted and selected.

Regression range

• I could reproduce this issue way back to 53.0a1. I think it's safe to assume that this is not a regression.

Additional notes

• Also, selecting an image has the same behavior as a simple text selection.
• Screencast attached to observe the issue.
