Infinite Download of Markdown Files

Nobody has claimed this yet.

Reported on behalf of anonymous user:
## The Issue
LBRY android application is contstantly downloading <...>.md file and doesnt stop (which cannot be shown in the app on my device)

### Steps to reproduce
1. Open an markdown file in lbry to read.
2. It shows a blank page instead of content
3. The file keeps being downloaded, you can see it in the notification bar. Visiting multiple markdown articles results in all those downloads that dont stop stacking up in notification area.

### Expected behaviour
Tell us what should happen

I should be able to click on markdown files,
read them in the app,
And the file should stop downloading.
### Actual behaviour
Tell us what happens instead

The markdown viewer in LBRY Android shows a blank page instead and continous downloading the file and it never stops, only when clicking (lbry service is running in the background "STOP") it stops, but when I restart lbry and view whatever random markdown content, those files appear again downloading in the notification area. Only thing that stops it is not opening and clicking markdown content.

Start by reproducing the issue in the LBRY Android app on the reported Android 9 device or an equivalent environment, focusing on the markdown viewer and download notifications. Trace the markdown opening and download flow; done means markdown content renders, downloads finish without repeated notifications, and the behavior is tested against the reported device and regression coverage.
