1908856 - Text-Fragments: It's not possible to create a selection on a text directive

Status: VERIFIED FIXED

(Core :: DOM: Selection, defect)

Description

[Jan Jaeschke [:jjaschke]]

STR:

• Enable dom.text_fragments.enabled pref
• Go to a page that has a text fragment, e.g. https://en.wikipedia.org/wiki/Nuclear_power#:~:text=up-,Most,reactors
• Try to select some text in the text by starting to drag inside of the target-text selection

Expected results:
Text can be selected.

Actual results:
Selecting is not possible. No visible selection is shown. Logging selectionchange events to the console shows that no selection change event is fired. Selecting something + Copying also does not work.

Starting to drag outside of the target text selection does work. Also selecting by double-clicking inside of a target-text area does work.
