Flow page does not properly display image links with HTML escape characters

1. Environment

• Device: [Xiaomi 14]
• OS: [Hyper OS/Android 14]
• APP: [0.10.1]

2. Describe the bug

In the flow page, some RSS items have escape characters in their image links. These pictures are not displayed correctly in the flow page:

I use tiny tiny rss as my server, I can see warning in my backend:

Undefined array key 1
1. classes/Handler_Public.php(758): ttrss_error_handler(Undefined array key 1, classes/Handler_Public.php)
2. public.php(49): cached()

User agent: ReadYou/0.10.1(25)

The correct url should be:

/public.php?op=cached&file=images/e7ac1d48a7bcc95006b095d6782beda581b2780c

Maybe this is duplicate of #824.
