On Linux, with either Firefox or Chrome, and EasyEDA Standard Edition, exporting to a PDF results in net label text overlapping the net label symbol and symbol pin numbers overlapping symbol pin names.

To reproduce this:

1. Create a new project, place a symbol (e.g. ESP32-S3-WROOM-1) on the schematic, place net labels on GND and 3V3, set the text of the GND label to GND and the text of the 3V3 label to 3V3 and note that the Text Anchor property defaults to "end" for each of them.

2. Select File -> Export -> PDF... Engine=Local and Type=Merged Sheet. Then click Export. In the resulting PDF, note that the net label text overlaps the net label symbol and the pin numbers overlap the pin names.

3. Go back to the schematic, click on the 3V3 label and change the Text Anchor property to "(Auto)" or "start". Export as a PDF and note that the 3V3 label is now in the correct position.

I have many archival PDFs where the net labels are positioned correctly. However if I go back to the original projects and re-export them, the net labels are now in the wrong position.

Not sure when this started happening, but it looks like a regression. It happens in both Firefox and Chrome on Linux:
