The fix for Bug 63955l introduced regressions. Armin Le Grand from bug 63955,
comment #18 said:

"Why was this fixed *in the primitive creation* ? Primitive creation should
always represent the 'truth' about the geometry. If decomposition takes too
long, the fix should be where it gets decomposed. Each decomposition
implementation at the primitive level *has* ViewInformation exactly for that
purpose (!)
Did I mention that for dashed lines when *clipping* against *something* the
dash *will move* and not be the same as when started from the line's start?

The fix also does not prevent a 18km long line be fed to rendering from other
sources, only one source is eliminated. That's why it should be fixed where it
gets visualized/discretized."

The regressions were worked around in Bug 120350 with a note suggesting to
perform clipping elsewhere:
