I was able to reproduce the problem mentioned, but I don’t think it is a bug.
I’ve tried to see how it works in Microsoft Power Point, and you have the
option to use really big values for width and in all cases, it will grow even
beyond the slide limits and overlap other borders that have the similar widths.

I think it is a case with boundary values and in my opinion, a solution would
be to use the menu that gives default and most used widths instead of a value
where you can grow it to 1.97”, in that case, we would have a limit of 6.0 pt.
and the option to use line width menu if we expand the option mentioned. That
way, we guide the user to the expected purpose of the tool and avoid them to
use really big values unless they really want to, because even mistyping a
number can draw really thick lines.

I have done also some follow-up tests to verify the relationship between these
configurations and drawing tools and I found the following behavior:

Mac OSX El Capitan
Open Office version 4.1.2

Steps:
1.    Create a new presentation using Impress/Presentation.
2.    Use Empty Template to avoid confusion with the background.
3.    Select Line tool in the menu at the bottom of the page and draw a line.
4.    Select Arrow tool in the menu at the bottom of the page and draw an
arrow.
5.    Select the arrow you draw and change the line type to fine dashed and the
width to 0.10”.
6.    Draw another line and verify it draws it properly without changing the
default configuration.
7.    Select arrow drawing tool again.
8.    Change the line type to fine dashed, update the width to 0.10”, use the
tool on the left of line design to define a different type of arrow and draw
the arrow.
9.    Arrow is properly drawn, but the arrow design is not updated.
10.    Select line tool and draw a line (it draws a line maintaining the format
given to the arrow, this means that updates line default configuration).
11.    Start increasing the width of the line, and you’ll notice it is not a
line, it is an arrow of the type you selected in step 8, that has the head of
an arrow in default size when it was drawn.

Expected Result:
Line tool should always draw a line, otherwise, what’s the purpose of having
line and arrow drawing tools.

Actual Result:
Line tool is drawing an arrow

What I found interesting here is that under line tab, you have options to
define line properties and arrow styles and besides you have another arrow
styles tab. In this case, the problem is that the option available to change
arrow types in the top menu is affecting the arrow styles section under line
tab when performing the change while selecting a drawing tool. This update
causes that future lines will be drawn as arrows.

I think this should be properly separated to avoid this type of confusions or
unify the line and arrow tools. It is really confusing for the user, because
you expect line tool to draw lines and arrow tool to draw arrows.
