Ruby text interferes with in-book search

[23452gdfg]

Search interference reported in 2056614 have been fixed but I found that in-book search is still effected by the same interference. This is reproducible with the same book and search terms.

to reproduce try to search for a phrase with ruby text in any Japanese book
for example in this phrase in the book
e4d52f1d833ed56920b040ef1045fd04 (libgen)
懇々(こんこん)と諭(さと)された
懇こん々こんと諭さとされた yields result while 懇々と諭された yield no result

expected behavior:
the sane form(懇々と諭された) should included in the search result not 懇こん々こんと諭さとされた

for 2056615 I've also added some possible solution
