The uselist is not a LC-praising lis
Indeed, the current implementation of
(Default),(Menu),(Message),(Styled Text),(System),(Text),(Tooltip)
is not very useful.
For example (System) at size 13 on MacOS 10.15 is on Windows 10
at about (System) at size 12. So one needs nevertheless a platform
switch.
Some people are very angry about deficiencies of LC, what I can understand from

This is possibly your problem if I understand correctly what

You try to work, using one LC method (styledText), around

As others try to optimize ("ping") I'll try an improvement too ("pong")

Then the following in the field's script does what you want.

if pUrl begins with "#" then

The htmltext of a field is based on HTML3 or before.
In HTML 3/4 a span can not contain two links, in HTML5 yes.
