Tooltip-text lingers if element gets deleted from DOM

[jmfk]

Describe the bug
I have a list of projects that each have a delete button with a Tooltip.
But when I press the button (the tooltip is active and showing) the text for the Tooltip gets hanging like a "ghost" text. It gets removed correct if the page reloads. It seems like since the definition of the Tooltip is removed it can't be cleaned up.

Code To Reproduce

import mesop as me

projects = [
    {"key": "hello", "text": "Hello", "tooltip": "This is a tooltip"},
    {"key": "world", "text": "World", "tooltip": "This is another tooltip"},
]


@me.stateclass
class State:
    select_message: str = "Nothing yet"
    delete_message: str = "Nothing yet"


def on_reset(e: me.ClickEvent):
    global projects
    projects = [
        {"key": "hello", "text": "Hello", "tooltip": "This is a tooltip"},
        {"key": "world", "text": "World", "tooltip": "This is another tooltip"},
    ]


def on_select_project(e: me.ClickEvent):
    state = me.state(State)
    state.select_message = f"Selected: {str(e)}"


def on_delete_project(e: me.ClickEvent):
    global projects
    state = me.state(State)
    state.delete_message = f"Deleted: {str(e)}"
    projects = [p for p in projects if p["key"] != str(e.key)]


@me.page(
    path="/",
    title="Tooltip Bug",
)
def app():
    state = me.state(State)
    with me.box():
        me.text(f"select_message: {state.select_message}")
        me.text(f"delete_message: {state.delete_message}")
        me.button(
            on_click=on_reset,
            label="Reset",
        )

    for project in projects:
        with me.box():
            me.text(project["text"])
            with me.tooltip(message="Remove Project"):
                with me.content_button(
                    on_click=on_delete_project,
                    type="icon",
                    key=project["key"],
                ):
                    me.icon(icon="delete_circle")

Finally got a chance to take a look at this. I tested it out and it seems to be working fine now. We did recently update the Angular version (though I don't think we updated Angular Components lib), so perhaps that fixed it?

I think we also fixed an issue recently with some components not being garbage collected correctly (leading to memory leak), so perhaps this was a side effect of that.

When I run the code and press delete on Home, the tooltip for World gets activated for me. But when I move away from the delete button World, the tooltip fades away.

Are you still seeing this behavior on 0.14.1?
