Is there a way to know whether the provided slot was invalid?
I have a plugin that uses onMacroRendererSlotted but the UI needs to be updated every few seconds and I use a JavaScript timeout for that.
However, when the user edits the block etc. the slot can become invalid.
Logseq detects this and prints a message like can not resolve selector target #slot__whppb9x3.
It would be great if provideUI could throw an exception instead of just printing to the console, so I can stop trying to update the invalid slot in this case.

Here are supported methods defined in https://github.com/logseq/logseq/blob/master/libs/src/helpers.ts#L422-L451

    'click',
    'focus',
    'focusin',
    'focusout',
    'blur',
    'dblclick',
    'keyup',
    'keypress',
    'keydown',
    'change',
    'input',
    'contextmenu',

Notice that use data-on-focusout instead of data-on-focus-out

Works fine except on-blur, which does not bubble.

In case I'm using onBlockRendererSlotted for a block, is it possible to keep rendering using Markdown? How does "template" work?

It would not be possible to pick up an exception when using setTimeout. There is a way to use the DOM and check if the element in question exists by doing something like const element = parent.document.getElementById("edit-block-UuidHere").

The Markdown is not lost during rendering, but many callbacks occur. A variable can be used to put a processing lock to the process. (let processing === false) Set it to true after processing. "provideUI" template is a the pop-up content. If the key is not changed, the content can be updated. It should be controlled so that it is not executed too frequently.
