/**
 * click_to_edit plugin for Tomselect
 *
 * This plugin allows editing (and selecting text in) any selected item by clicking it.
 *
 * Usually, when the user typed some text and created an item in Tomselect that item cannot be edited anymore. To make
 * a change, the item has to be deleted and retyped completely. There is also generally no way to copy text out of a
 * tomselect item. The "restore_on_backspace" plugin improves that somewhat, by allowing the user to edit an item after
 * pressing backspace. However, it is somewhat confusing to first have to focus the field an then hit backspace in order
 * to copy a piece of text. It may also not be immediately obvious for editing.
 * This plugin transforms an item into editable text when it is clicked, e.g. when the user tries to place the caret
 * within an item or when they try to drag across the text to highlight it.
 * It also plays nice with the remove_button plugin which still removes (deselects) an option entirely.
 *
 * It is recommended to also enable the autoselect_typed plugin when using this plugin. Without it, the text in the
 * input field (i.e. the item that was just clicked) is lost when the user clicks outside the field. Also, when the user
 * clicks an option (making it text) and then tries to enter another one by entering the delimiter (e.g. space) nothing
 * happens until enter is pressed or the text is changed from what it was.
