Bug: Can't draw aux lines in some rows/cols in division type puzzle (e.g. fillomino, double choco)

Hello,
I can't draw auxiliary lines in some rows and columns, in "division" type puzzle (such as Shikaku, Fillomino, Double Choco, etc.)
Rows/cols number with bug might change on size change.

That's curious... It works for me. Some things that would be useful to nail this down:

• does it happen with all browsers? what browser and OS are you using?
• do you see the same with pzv.jp?
• does zooming change it? (by browser or using Display->Cell Size in the menu)

I wonder whether the aux lines are actually not being drawn, or just not being displayed. You might be able to help find that out by trying to draw the missing aux lines and then looking at the "duplicate board" URL (or sharing it here). E.g. a 2x2 double choco with two aux lines is encoded as

https://puzz.link/p?type=editor&pzprv3/dbchoco/2/2/. . /. . /-1 /0 /-1 0 //

I think the -1 stands for aux line, while 0 stands for no aux line.

Thanks for response.
I confirmed that the aux lines are actually drawn, but they are simply not displayed due to the cell size or browser's zoom size.
It doesn't happen on pzv.jp.

My environment:

• OS: Windows 11 Home
• Browser: Google Chrome , Microsoft Edge (both are the latest version)
