Converting `href-sanitizer` scriptlet to uBO version is incorrect

[piquark6046]

Currently, the following AG scriptlet is converted from

ppomppu.co.kr#%#//scriptlet('href-sanitizer', 'a[href^="https://s.ppomppu.co.kr?"][href*="&target="]', '?target', 'base64decode')

to

ppomppu.co.kr##+js(href-sanitizer, a[href^="https://s.ppomppu.co.kr?"][href*="&target="], ?target, base64decode)

However, it should be

ppomppu.co.kr##+js(href-sanitizer, a[href^="https://s.ppomppu.co.kr?"][href*="&target="], ?target -base64)
