A while ago we made a change to display a warning after installing a theme component when the admin tries to leave the page without adding the new installed component to any themes (see https://github.com/discourse/discourse/commit/5e29ae3ef5f7ad33906d00314cbdfb3a2813c529).
However there is an edge case that we forgot to address, and that's when an admin installs a component and then immediately opens the install modal again to install another one which can result in the warning being shown twice at the same time.
This PR prevents that by showing the warning when opening the install modal if the conditions are met (new component and not added to any themes) instead of showing it after installing the second component.
Installing multiple copies of the same theme/component is possible, but you rarely need to actually have multiple copies installed. We've seen many times new admins installing duplicates of components because they were unaware it was already installed. This PR makes the theme installer modal loop through the existing themes when you click on 'install', and if there is a theme with a URL that matches the URL you entered, a warning will show up and you will need to click 'install' again to proceed.
When you type # or @ in the search box, a popup appears with
autocomplete suggestions. Currently, when the popup is rendered it has
the first item selected and upon pressing Enter, the first item is
inserted into the search box. The problem with this behavior is that the
first suggestion may not be what you want, and if you are typing quickly
and hit enter, the first suggestion (which is not what you want) is
inserted in the search box.
This PR amends the popup so that it has no suggestions selected by
default which means the enter key will not insert anything unless you
select a suggestion via the up or down arrow keys.
The notification panel gets resized and the JS uses maxWidth of 320.
This tends to fight with the CSS causing notifications to "jump" a bit when a new one lands.
Scrolling was not working as expected after clicking the browser back button and navigating back to the tag topic list. We need to wrap the scroll inside a debounce function to ensure that the "window.pageYOffset" property is populated before our function runs.
