[Bug] Js and Css are injected twice on the text.

[Palloxin]

Steps to reproduce

1. Take a freshly installed version of lnreader 1.1.19
2. AllNovelFull, Hidden marriage, add to the library
3. Download chapter 1 and 2
4. Inject this JS:

alert(chapterName)

5. Open chapter 1, scroll until the bottom and click "Next chapter" (see video below).

Expected behavior

• Js and css applied only once so the alert should popup only once.

Actual behavior

Js applied twice when the chapters in question are downloaded.

LNReader version

1.1.18 and 1.1.19(the bug exists since the first time i started using lnreader so.. 1.1.15.1, idk previous versions)

Android version

Android 8 Miui 8

Device

Other details

This issue has been almost completely rewritten on 4th November 2023
It is a re-opened issue because devs couldn't reproduce it even with the video so i think one needs to guess the cause of it correctly to fix it or test it on android 8.

EDIT: another re-edit in 9th of June 2024

Not able to reproduce this with simpler scripts.

Your custom JS might be replacing / setting the HTML content more than once which could probably cause this.

Here you can see that the JS has been applied already when the chapter loaded, then It lagged a bit, the chapter resetted and the JS applied again before the chapter_progress_resume feature activated. You can see it by the string 0.5 becoming 0.1999999284.
