Some high-cardinality tags hide a value in the Tag Details UX

### Environment SaaS (https://sentry.io/) ### Steps to Reproduce We have one tag on a particular issue that seems to hide one of the values in the UX. This same tag on other issues loads ok, and we haven't seen any other issues/tags with this problem in our spot checking, even those with many unique values. The tag in question has 10.6k distinct values on the problematic issue. This is reproducible between several users for this particular issue & tag on our instance Full details, including links and a recording of the problem, are available on the internal customer case 1. Open one of the problematic issues 2. Click "View All Tags & Flags" (it might be "View all tags and feature flags" as well depending on UX version or distribution or something?) 3. Observe that the problematic tag has a top value of X, with %x, and the second highest value of Y with y%. In our example, it's 65%, 34%, <1% for the third value, and then Other: 1%, and tag name of `bucket_id` 4. Click on the tag to view full details, which opens the "Tag Details - $tag_name" pane. ### Expected Result The details should show the same X, Y, and following tag values with the correct % and counts ### Actual Result The details miss X, and display only Y and below. It uses the same y% as before, so in our example the Share does not add up to 100% NOTE: the network request to `https://us.sentry.io/api/0/organizations/$org/issues/$issue/tags/$tag_name/` does return X, so it seems like a UX problem. ### Product Area Issues ### Link _No response_ ### DSN _No response_ ### Version _No response_
