What is the expected behavior?

Given my app image size of 2531728, I expect it to boot from OTA_1 when I use otatool.py to switch it to that partition. The partition table I have:

I (60) boot: ## Label            Usage          Type ST Offset   Length
I (67) boot:  0 nvsfs            WiFi data        01 02 00009000 00004000

I (127) boot: End of partition table

What is the actual behavior?

Instead it boots from OTA_0. If the image size is below 2M to fit in 16M boundary, then it boots fine from OTA_1

Steps to reproduce.

Create a partition table with OTA_1 near 16M address
Create and build an application image with size that will cross 16M address boundary when flashing it at OTA_1 using esptool 4.5.1
Use otatool to switch booting from OTA_1 .

This is because cache cannot map over 16MB address on v4.4, it will support this on 5.1
