Notifications and Communities buttons not responding to icon clicks

+10

−0

Previously, clicking on the icon for Notifications or Communities at the top right of the page resulted in the appropriate drop down panel appearing. Today, the panel only opens if the square area around the icons is clicked. Clicking on the icons themselves does not open the panel (although it still works for closing the panel).

Panels only open when clicking around the edges rather than on the icons

On the desktop site this is confusing, but can be worked around by remembering to click the edges once you know to do this. However, on the mobile site touching a small area around the edge of the icon is more challenging, making navigating the mobile site difficult.

On mobile one other button is affected: the hamburger menu (3 horizontal lines icon) at the top right of the page. As this is a bigger icon it is more difficult to touch the space around it without touching the icon. I find I need to zoom in to make the space around the icon easy to touch, then zoom back out to view the panel that has opened.

I don't know if there are any other similar buttons affected in this way. I've tested that the reactions panel opens fine, but that involves clicking on text rather than an icon.

HTML

In terms of HTML tags, clicking on the <a> tag directly works fine, but clicking on the  tag (for the blue notification circle with a number in it) or the  tag (for the Notifications envelope icon or the Communities down arrow icon) only works for closing the panel, not opening it.

In case it's related: I saw this behaviour on my first use of the site after the recent code release

trichoplax‭ we deploy from develop, but after a change gets made in co-design it then needs to propagate to qpixel and then be deployed, and I'm not sure where that stands.

@ArtOfCode tonight I noticed that this bug doesn't occur with the mod menu; I clicked on the word "mod" rather than under it and it took me to the flags page as I expected. Is the code for that one different somehow?

Thanks for explaining, Monica.

As for the mod menu, I don't have access to it, not being a mod here, but Canina's comment on this same Meta post may give a clue. It sounds like buttons that have an icon have the problem, but buttons that just have text are unaffected.

This would be consistent with the underlying cause, that a click on a nested HTML element is what triggers the problem.

For a button with an icon, the HTML looks something like this (simplified for illustration):

<a>        // The <a> element corresponds to the whole "button"
    <i>    // The <i> element inside the <a> element corresponds to the icon image
    </i>
</a>

Clicking on the icon (the  element) triggers the bug in the code, which closes the panel before the user has time to see it has opened (for all practical purposes, the panel never opens).

Clicking in the whitespace around the icon avoids clicking on the  element so only the <a> element is clicked on, resulting in the panel opening successfully.

For a button with only text, the HTML looks something like this:

<a>        // The <a> element corresponds to the whole "button"
    Text   // The text inside the <a> element does not have an additional <i> element
</a>

Clicking on the text counts as clicking on the <a> element directly, as there is no nested  element, so the bug is not triggered.
