Gitea treat JS errors seriously, so sometimes the JS errors caused by 3rdparty code (eg: browser extensions) would also be reported on Gitea UI: TypeError: WeakMap key undefined (caused by extension DarkReader's bug) #28861 To avoid fill the user's screen with a lot of error messages, this PR merges the same error messages into one, like this: ```js <div class="page-content"> <div class="... js-global-error" data-global-error-msg-compact="testmsg1" data-global-error-msg-count="2">test msg 1 (2)</div> <div class="... js-global-error" data-global-error-msg-compact="testmsg2" data-global-error-msg-count="1">test msg 2</div> </div> ```
