> Trailing whitespace seems to trigger a weird issue where text contents are thrown right
a lot more than expected. It's as if "text-anchor" inheritance was no longer honored in these
cases (and reset to "start", the lacuna value).
> Bug's URL points to a thread ("JSVGCanvas Problems - Rendering and Writing") which contains
the original test case and a modified test case which doesn't reproduce the issue (basically,
with trailing whitespace trimmed).
> According to the thread, the issue doesn't seem to reproduce on Linux. Can anyone else
confirm and provide information for MacOS as well?
> BATIK-689 seems tightly related, although the issue is not quite the same (it refers
to a MacOS-specific issue). Also, thread "tspans fail to line up" [1] seems related as well.
I wonder if all these are the same...?
> A possible workaround is to make sure tspan elements don't contain trailing whitespace.
