I noticed a few anomalies:
The new "Show only MQA" feature, which is only displayed if there is any MQA content in the current display, was not correctly collapsing the space left behind on screen when non-MQA content was filtered out
Under particular conditions it was possible while scrolling through browse results, to end up with duplicates on the displayed results
Some browsers throttle the background JavaScript on inactive tabs, which manifests itself here in the progress bar not being correctly updated for the currently playing track
Happy to report that all of the above have now been resolved 😀
