System Information
Operating system: Windows-10-10.0.18362-SP0 64 Bits
Graphics card: GeForce GTX 1080/PCIe/SSE2 NVIDIA Corporation 4.5.0 NVIDIA 442.59

Blender Version
Broken: version: 2.90.0 Alpha, branch: master, commit date: 2020-07-05 20:45, hash: baf124c753
Worked: version 2.83.1

Short description of error
Bevel on edge that belongs to uv border does not give correct behaviour in uv editor. This worked in blender 2.83.1

Exact steps for others to reproduce the error

Create default cube and enter edit mode
Select edge with index 2 on default cube

Bevel with amount of segments not dividable by 2 (e.g 1, 3, 5, 7 etc)

Detailed error description

Edge belongs to uv boundry
Bevel operator has amount of segment that are not dividable by 2 (e.g. 1, 3, 5, 7 etc)
Is not edge with index 0, 4 or 10 on default cube??!?!?!!?!

{F8677894, height = 200} Starting point	{F8677897, height = 200} Bevel segments = 2 has desired uv behavior	{F8677899, height = 200} Bevel segment = 1 has undesired uv behavior
{F8677910, height = 200} Starting point	{F8677912, height = 200} Bevel segments = 2 has desired uv behaviour	{F8677920, height = 200} Bevel segment = 1 has desired uv behaviour, but I can not figure out why since other border edges does not work. The edges marked with green with index 0, 4 & 10 has desired uv behaviour for unknown reason

[Based on the default startup or an attached .blend file (as simple as possible)]
