ESPAsyncwebserver template processor bug - size related?

I have a bug on the /system/ page, I also noticed it on /wifi/ page sometimes, not reproducable everytime. So i am glad, the bug also appears here 100% reproducable

I inserted `<li><a class='' href='/system/sensor/'>&#x1F321;&#xFE0F; Sensor configuration</a></li>` to the /system/ html template. With this included, the template processor will corrupt the final output when processing %FOOTER%, which got inserted from AddHeaderFooter() function.

the rendered output, damaged, looks like this

```
<input type='submit' value='&#x1F4BE; Save settings'>
</form>
<div cla%</span></div>
</div></body></html>
```

notice that the div on the second last line is broken at `class` - got `<div cla%</span></div>`.

It should look like this: 

```
<input type='submit' value='&#x1F4BE; Save settings'>
</form>
<div class='footer'><span>Build: 92724fa-esp8266-20241102171544</span></div>
</div></body></html>
```

-# CanGrow - Arduino Code
+# CanGrow - An OpenSource grow controller firmware
 
-Here the Code for CanGrow is contained. 
-A ESP8266 with Arduino Firmware is used (should most times be the standard already).
+## Build environment
+The helper script `cangrow.sh` is written for a Debian 12 system. 
+
+To install all dependencies you need for building the firmware, run the cangrow.sh setup:
+
+```sh
+$ ./cangrow.sh help
+./cangrow.sh [setup|build|upload|webupload|monitor]
+setup: setup build environment, download arduino-cli, install all dependencies for arduino ide
+build: build firmware binary. will be saved into build/
+upload: upload firmware by serial connection /dev/ttyUSB0
+webupload: upload firmware with webupload to 192.168.4.20
+monitor: serial monitor /dev/ttyUSB0
+
+# Install all dependencies for build environment
+$ ./cangrow.sh setup
+```
+
+The script installs [arduino-cli](https://github.com/arduino/arduino-cli) to `~/.local/bin/arduino-cli`. 
+
+## Compile
+
+```sh
+# compile and output to build/CanGrow_v0.2...bin
+# Default Target is ESP8266 D1 Mini
+$ ./cangrow.sh build
+
+# Compile for ESP32 D1 Mini
+$ export BOARD="esp32:esp32:d1_mini32"
+$ ./cangrow.sh build
+
+# Build and webupload to IP
+$ export IP="192.168.4.69"
+$ ./cangrow.sh build # need to make .bin first
+$ ./cangrow.sh webupload # upload
+
+# listen to serial monitor on /dev/ttyUSB2
+$ export TTY="/dev/ttyUSB2"
+./cangrow.sh monitor
+```
+
+I wrote this project using [Geany IDE. ](https://www.geany.org/). The Geany Projectfile is also included, just run
+```sh
+$ geany CanGrow.geany
+```
 
-I wrote this project using [Geany IDE. ](https://www.geany.org/). The Geany Projectfile is also included. 
-Compiling is done with [arduino-cli](https://github.com/arduino/arduino-cli). It is supposed to be in
-`~/.local/bin/arduino-cli`. 
 **F8 compiles** the project, **F9 uploads** firmware to /dev/ttyUSB0. You can change these settings for .ino and .h files
 in Project -> Settings -> Create/Make.
