UT2004 server make heavy load for browser

[SeriousBuggie]

Reproduce:

1. Open http://beta.openspy.net/en/server-list/ut2004

Expected result: While page load, browser act responsively, like possible switch to another tab.
Actual result: browser freeze as hell, and switch to another tab with significant delay, like 20-40 seconds.

Used Firefox 115.1.0esr 64-bit on Windows 7.

Possible reason - country flags put on page as objects (use object tag). It is SVG images, and can be put as images (img tag).
As result - same resources ask again and again. Which make DoS attack on web server and create other issues.

Here net console: Cache turn on, but this not help. Same resources request again and again:

<td _ngcontent-olm-c17="" class="fiag-icon"><object _ngcontent-olm-c17="" type="image/svg+xml" data="assets/flags/us.svg"></object></td>
