It does not seem to be possible to select the characters of an email address or a web link without selecting the bullet point of an item. This only happens if the item is an email address or web link with nothing else on the item's line. If normal text appears after the email address or web link, you can select any text in the item without the bullet point.
Steps to recreate:
1-create a new bullet point item that is only an email address
2-Click enter to go to a new line.
3-Attempt to select all the text of the email address by clicking on it does nothing. Attempting to click on the first character and drag to the last character causes the bullet point to be included in the selection. The same is true of clicking the last character and dragging to the first character.
4-You cannot partially select any character in the email address.
If you use mouse to click at the start or end of the email address, you can then use the cursor to partially select characters in the email address as expected, but the bullet point is always included once you have cursor-ed over the final character.
This does not happen with "Project" characters but does with "Bullet Points"
If the Bullet Point (unlike the Project icon) is considered by Legend to be "just another character" in the item's text, it should be selectable (or not) as any character in the item.
