Hello,
I have Emacs 28 on one machine and this build 29 on this machine--both running on Windows 10. I've encountered the same bug on both builds of Emacs. I believe it's a bug.
To reproduce the behavior, first make a link that begins a line, such as:
Org Mode will turn the above text into a clickable link called "link".
Now, select the link either by clicking and dragging the mouse from the end of the word "link" to the beginning of the word, or by starting a region at either the beginning or end of the word (or on the next line) and then using the arrow keys to move point to either the "l" or "k" in "link".
Your region should now encompass "link" and nothing else.
Now, kill the line or region.
You will see immediately that the full text was not killed. Instead, the link description is killed, along with, depending on where point was, possibly some of the brackets, leaving behind the opening brackets, the link URL, the URL closing bracket, and in some cases the final two brackets.
This behavior does not occur if the link is not at the beginning of a line. For example, write this instead:
Now, mark the same area, just the link that Org Mode has made, called "link", using the mouse or using a region demarcated by using the arrow keys.
Now, kill the link.
You will see that the full link has been killed. Yank to confirm.
I believe org mode is not correctly finding the last characters to select before either the beginning or end of the line in these use cases.
Thank you!
