When I highlight a line of text on a post I am composing, sometimes the text un-highlights itself, and focus returns to the textbox.
Steps to reproduce:
- Navigate to the "Ask a Question" page, for example by using the "Ask Question" link.
- Enter text into the text box. Text will appear in the preview window.
- Highlight part of one line of the text in the preview window.
When you release the mouse button after highlighting, the text will no longer be highlighted, and the cursor in the text box will resume blinking.
Recordings of bug:
This happens even if the line wraps, like so:
But the text does remain highlighted as expected if I highlight multiple lines, like so:
Additional information:
This happens on every page I have tried that has a preview window – asking a question, answering a question, or editing a post.
This happens on every Stack Exchange site that I have tried – Stack Overflow, Meta Stack Exchange, and Board & Card Games.
