QuickPick ignores matchOnDescription/matchOnDetail being false

[JWaters02]

Description

In the vscode extension I am working on, I have a quick pick like so:

When I type a string, it tries to filter the checked items by the string, as if it is searching. However, in my code, I have

quickPick.matchOnDescription = false;
quickPick.matchOnDetail = false;

which shouldn't be needed anyway as they are false by default, but I thought I'd try this for the benefit of the doubt.

So the quick pick is ignoring the matches being false. Which is incredibly frustrating.

Here is the code I have to create the quick pick:

        const quickPick = vscode.window.createQuickPick();
        quickPick.placeholder = vscode.l10n.t("Enter the text to search for.");
        quickPick.items = [
            {
                label: vscode.l10n.t("Use Regex"),
                description: vscode.l10n.t("Should your search string be considered a regular expression?"),
                picked: false,
                iconPath: new vscode.ThemeIcon("regex"),
            },
            {
                label: vscode.l10n.t("Case Sensitive"),
                description: vscode.l10n.t("Should your search be case sensitive?"),
                picked: true,
                iconPath: new vscode.ThemeIcon("case-sensitive"),
            },
        ];
        quickPick.canSelectMany = true;
        quickPick.ignoreFocusOut = true;
        quickPick.matchOnDescription = false;
        quickPick.matchOnDetail = false;

        quickPick.show();

        quickPick.onDidAccept(async () => {
            const searchString = quickPick.value;
            if (!searchString) {
                quickPick.dispose();
                return;
            }

            const options = quickPick.selectedItems;
            const regex = options.some((option) => option.label === "Use Regex");
            const caseSensitive = options.some((option) => option.label === "Case Sensitive");

            quickPick.dispose();

            // do some stuff on the selected items here
        });

Also, there is another bug that is likely related (and I don't know if should be seperate bug report), that in my quickpick, I have one of the items as picked: true (as you can see in the code above), but when the quickpick shows, the item is not actually picked/ticked already (as you can see in the demo video).

See the documentation on picked

Optional flag indicating if this item is picked initially. This is only honored when using the showQuickPick() API. To do the same thing with the createQuickPick() API, simply set the QuickPick.selectedItems to the items you want picked initially. (Note: This is only honored when the picker allows multiple selections.)

quickPick.matchOnDescription = false;
quickPick.matchOnDetail = false;

Just means that the description & detail will not be considered when determining a match. In other words, when we determine if an item should show up, we will not search the description/detail for a match of the query.

If they are true, then the description/detail will be searched in addition to the label.

From your gif, this appears to be working as intended.

If you are trying to show items when nothing matches, maybe you can play around with the alwaysShow property:
