Issue 1:
When Find/Replace dialog is not open,
R-click a regular-expression whole-word-only marker and select “Replace…”
Now Replace dialog is open.
** But “Use Escape Sequence” option is also checked. And “\” in the string changed to “\\”.
When Find/Replace dialog is open, with options unchecked,
R-click a regular-expression whole-word-only marker and select “Replace…”
** The options are not set correspondingly.
When Find/Replace dialog is open, with both “Use Regular Expressions” and “Use Escape Sequence” checked,
R-click a regular-expression whole-word-only marker and select “Replace…”
** “Use Regular Expressions” is off.
Issue 2:
Such a Marker-to-Replace transfer never triggers the matched FRP.
