Export EPUB: <br> missing on every exported EPUB

[Palloxin]

Steps to reproduce

1. go to Panda Machine translations
2. search Into the Creations and download chapter 1
3. export the novel (so only chap 1) with js included(because i did so and i dont want to test if it appears when i dont include JS)
4. check with an editor the extracted html of chap 1 (of the epub, see images below)

Expected behavior

(This a simple screenshot from Lnreader reader of the chapter so i expect the epub to be reproduced the same as in Lnreader, aesthetically)

Actual behavior

(Into an epub3 reader)

Looking into the html file u can see this

(so it is not the JS fault)
Whatever there was there in the chapter when using lnreader, it is not present in the extracted epub.

EDIT: every <br> is missing

LNReader version

1.1.16

Android version

Android 8 miui 8

Device

Huawei p8 lite 2017

Other details

No js applied in the text of the image in Expected Behaviour.

Not just missing on exported EPUB, but probably in imported as well!

I made the EPUB file myself in Calibre and imported it to the app. Found that LNReader is not rendered <br/> properly so I come here to see if there's an existing issue. At first I just thought that the app has issue on rendering HTML or something similar, but @Palloxin screenshot show the downloaded text rendered <br/> correctly. So the issue is something remove <br/> during import/export EPUB process?

Edit: I edit comment because GitHub actually line break <br/> in the comment that I forgot to marked as code...
