[Bug]: fish could not read response to Primary Device Attribute query

[dclong]

Current Behavior

Running fish (latest version 4.6) in waveterm (latest version 0.14.4) generates the following warning message.

warning: fish could not read response to Primary Device Attribute query after waiting for 10 seconds. This is often due to a missing feature in your terminal. See 'help terminal-compatibility' or 'man fish-terminal-compatibility'. This fish process will no longer wait for outstanding queries, which disables some optional features.

Expected Behavior

Waveterm supports Primary Device Attribute query so that the above warning message doesn't show and the fish shell starts faster.

Steps To Reproduce

1. install the latest version of the fish shell (using HomeBrew)
2. Download the latest AppImage of waveterm.
3. Start waveterm
4. Run the fish shell.

Hello, please fix. Fish is a very popular shell. Oddly, I can't tell if anything is actually broken (I haven't experienced any issues that I can point to), or is it just that fish unsuccessfully tries to detect some terminal feature.
