Comment (by eedithotter):

 The issue you're describing relates to WordPress development, particularly
 with the Twenty Fourteen theme and its Ephemera Widget. The core problem
 is that the Ephemera Widget doesn't account for the potential changes that
 plugins can make to the content through the the_content() filter,
 especially in terms of adding or modifying HTML, CSS, and JavaScript.

 When plugins like QuickShare are used, they often filter the_content() to
 add elements like social sharing buttons. The Ephemera Widget, however,
 doesn't recognize these changes. This oversight becomes apparent when the
 plugin is uninstalled. While the associated CSS/JS files are removed, the
 HTML markup added by the plugin remains. This results in a poor user
 experience as the remnants of the plugin are still visible even after its
 files are deleted.

 To replicate this issue:

 Install and activate a plugin (e.g., QuickShare).
 Add the Twenty Fourteen Ephemera Widget to a sidebar.
 Uninstall the QuickShare plugin.
 Observe that the HTML necessary for QuickShare's functionality still
 persists in the widget. Removing and re-adding the widget can temporarily
 fix this issue.
 One potential solution is to prevent plugins' filters from applying to the
 widget's the_content(). This approach would ensure that the widget's
 content remains unaffected by plugins, which is generally preferable for
 widget display. Another workaround, as you mentioned, is using CSS to hide
 specific elements from the widget.

 To address this issue more effectively, it might be necessary to modify
 the Ephemera Widget's code to either exclude certain filters or to refresh
 its content upon plugin deactivation. This could involve adding WordPress
 hooks or filters specific to the widget's behavior. Additionally,
 collaborating with plugin developers to ensure better compatibility and
 cleaner deactivation processes could also be beneficial.
