[UI Tests] - Long press on image gallery disrupting test flow

[jostnes]

The issue

For the e2ePublishFullPost test, an unintended long-press keeps happening, breaking the flow of the test and failing it. We have attempted to fix this, the latest in this PR: #17323 however, it doesn't look like the issue is fixed.
