Trying to add highlighting by starting the drag directly above the comment above the base content text may not work

[rakunavi]

Hello all,

I have found that when comments are placed above the base content text, trying to add highlight by dragging the mouse from directly above the comment may not work.

The sample file consists of two pages, with comments placed on the left and right side of each page. The blend mode of the comment on the left side of the page is set to "Normal", and the blend mode of the comment on the right side of the page is set to "Multiply".

In the following video, highlight comments are added in the following order with Exclusive mode enabled

1. Left side of page 1 (Line Comment, Blend mode: Normal)
2. Right side of page 1 (Line Comment, Blend mode: Multiply)
3. Left side of page 2 (Rectangle Comment, Blend mode: Normal)
4. Right side of page 2 (Rectangle Comment, Blend mode: Multiply)
5. Left side of page 2 (Rectangle Comment, Blend mode: Normal)
6. Left side of page 1 (Line Comment, Blend mode: Normal)
7. Right side of page 1 (Line Comment, Blend mode: Multiply)

Yellow highlight is added in the first round, and green highlight is added in the second round. Throughout, the mouse is dragged so that the highlight starts directly above the comment line. Note that ScreenToGif, which is used for screen captures, temporarily highlights the mouse cursor yellow while the left mouse button is held down.

  The capture software used (ScreenToGif) displays a yellow circle around the mouse cursor when the left mouse button is clicked.

As you can see in the video, in Step 1 through Step 3, no highlight can be added at all. However, in Step 4, for some reason, you can add a highlight. It would seem that if the exclusive mode is enabled, then highlighting should be possible even in Step 1 through Step 3.

What is even more curious is that when you go back to the left side of page 2 in Step 5 and add a highlight, you can somehow add a highlight that you could not add in Step 3, even though you went back to the left side of page 1 in Step 6 and to the right side of page 1 in Step 7, you can add highlights in the same way.

However, if you change the highlight color to green, you will not be able to add highlights again as before. The rest of the steps are the same as in the first round. Note that besides changing the highlight color, the exact same effect can be achieved by adding a highlight where there is no comment.

Hoping that the above information will be of some help to you.
Thank you so much for your continued support.

Best regards,
rakunavi

Hello, rakunavi

Thank you for the detailed breakdown, in my own testing, I found that this is not exclusive to the highlight tool, but seems to affect all of the "text commenting" tools, so I have made note of that in my message to the Dev team. I will let you know if I hear back from them on this.

[Edit]
Confirmed fixed for next release (397)

Kind regards,
