Over watering or fungus and I am leaning to fungus. Better safe than sorry, dont let it run down the stem into the root. Full sanitation, clorox the scissors and spray it with fungicide before you touch it to cut it and dislodge a spray of spores everywhere.
Why Do Elephant Ear Plants Get Brown on Edge? The most common reason for the phenomenon is simply leaf scorch. In high light, they may get burnt along the edges of the arrow-shaped leaves. This won’t kill the plant but does affect the appearance of the glossy foliage, which is the focal point of the ornamental plant. Provide bright light but shield the plants when temperatures are scorching, especially when the heat of the day is highest. In this case, it is easy to prevent the edges of elephant ear turning brown by positioning a garden umbrella to provide shade, tilting the blinds a bit for indoor plants, or relocating it to a region of the garden where some dappling occurs at midday.
What is strange about the elephant ear plant is that the more you primp with them the worse they do. I found several specimens while kayaking in southern Florida that were out in the wilds and grew to 8 feet tall. A couple were over 20 feet wide with leaves 3 feet long. Then I see people pampering them in their yard and getting leaves 12” long at best.
