BUG REPORT:

When reading an email, users can't drag the mouse pointer right-to-left to select text. The moment the mouse button is released, the blue highlighting disappears, and the text cannot be copied.

This does not happen when dragging left-to-right.

For decades, apps and web pages didn't care which direction you drag your mouse pointer. Text selection was successful either way.

This bug is a significant regression in user experience. Please restore standard mouse selection behavior.
