Fix this source: Royal Road watermark is back

[Xampa5]

App Version: 3.7.4

Describe this issue

Royal Road's 'invisible' text watermark is back.

I download novels to read them offline on my oled smartphone screen and this permanent nagging in the middle of every chapter is infuriating and gets me out of the story.

I know it's supposed to be handled around line 80 of royalroad.py, but not how to fix it

if style.endswith("{display:none;speak:never;}"): classnames.append(style[1:-27])

EDIT: I've been able to fix it in post using Calibre editor. At least for the 8 novels I downloaded today, the only time there's a paragraph followed by a div, it's the nagging watermark. Which can be found with the regex
<\/p><div>.*<\/div>

Ctrl+F, Find: <\/p><div>.*<\/div>, Replace: </p>, Mode: Regex, All text files, click Replace all.
