Hyphen in HTML link created from cross reference

In my FM2017 document there is a cross reference to text in a table column which has a hyphen in it.

Example:

column 1  | column 2

--------------------

some loo- | ...

oong text | ...

The cross reference in FM looks correct, with no hyphen if the line is long enough.

Example:

see "some loooong text" on page 123

In the generated HTML5, however, the hyphen shows in the original position, although it is unnecessary here.

Example:

some loo-oong text

This effect occurs both with an automatically inserted hyphen (by FM itself) and with a soft hyphen (CTRL + hyphen). Any ideas what else I could try?
