ATOM feed returns inconsistent data

Let’s have feed dvorka’s Activity

This feed at this point contains article “dvorka created a branch dev/2.4.0 in dvorka/hstr”. This article contains this HTML as its content:

<div class="git-branch" data-test-selector="visible-event"><div class="body"> <!-- create --> <div class="d-flex flex-items-baseline border-bottom color-border-secondary py-3"> <span class="mr-2"><a class="d-inline-block" href="/dvorka" rel="noreferrer"><img class="avatar avatar-user" src="https://avatars.githubusercontent.com/u/2090143?s=64&amp;v=4" width="32" height="32" alt="@dvorka"></a></span> <div class="d-flex flex-column width-full"> <div class="d-flex flex-items-baseline"> <div> <a class="Link--primary no-underline text-bold wb-break-all d-inline-block" href="/dvorka" rel="noreferrer">dvorka</a> created a branch in <a class="Link--primary no-underline text-bold wb-break-all d-inline-block" href="/dvorka/hstr" rel="noreferrer">dvorka/hstr</a> <span class="f6 color-text-tertiary no-wrap ml-1"> <relative-time datetime="2021-06-26T16:29:47Z" class="no-wrap">Jun 26, 2021</relative-time> </span> </div> </div> <div class="Box p-3 mt-2"> <div> <div class="f4 lh-condensed text-bold color-text-primary"> <a class="css-truncate css-truncate-target branch-name v-align-middle" title="dev/2.4.0" href="/dvorka/hstr/tree/dev/2.4.0" rel="noreferrer">dev/2.4.0</a> in <a class="Link--primary no-underline text-bold wb-break-all d-inline-block" href="/dvorka/hstr" rel="noreferrer">dvorka/hstr</a> </div> <p class="f6 color-text-secondary mt-2 mb-0"> <span>Updated Jul 25</span> </p> </div> </div> </div> </div> </div></div>

Problem is that the part Updated Jul 25 is often changed to Updated Jul 24 in the feed and back to Updated Jul 25 repeatedly each 2-5 minutes, resulting in problems with some RSS Readers which think that article was changed and acts accordingly. For example: [BUG]: If title of article changes, the article adds as new one · Issue #451 · martinrotter/rssguard · GitHub
